# MathLive

### Modules

These attributes of the <math-field> element correspond to the [MathfieldOptions] properties.

default-mode: string
fonts-directory: string
horizontal-spacing-scale: string

Scaling factor to be applied to horizontal spacing between elements of the formula. A value greater than 1.0 can be used to improve the legibility.

#### deprecated

Use registers \thinmuskip, \medmuskip and \thickmuskip

inline-shortcut-timeout: string

Maximum time, in milliseconds, between consecutive characters for them to be considered part of the same shortcut sequence.

A value of 0 is the same as infinity: any consecutive character will be candidate for an inline shortcut, regardless of the interval between this character and the previous one.

A value of 750 will indicate that the maximum interval between two characters to be considered part of the same inline shortcut sequence is 3/4 of a second.

This is useful to enter “±” as a sequence of two characters, while also supporting the “±” shortcut with the same sequence.

The first result can be entered by pausing slightly between the first and second character if this option is set to a value of 250 or so.

Note that some operations, such as clicking to change the selection, or losing the focus on the mathfield, will automatically timeout the shortcuts.

keypress-sound: string

When a key on the virtual keyboard is pressed, produce a short audio feedback.

The value of the properties should a string, the name of an audio file in the soundsDirectory directory or ‘none’ to supress the sound.

keypress-vibration: boolean
letter-shape-style: string
locale: string

The locale (language + region) to use for string localization.

If none is provided, the locale of the browser is used.

math-mode-space: string

The Latex string to insert when the spacebar is pressed (on the physical or virtual keyboard). Empty by default. Use \; for a thick space, \: for a medium space, \, for a thin space.

plonk-sound: string

Sound played to provide feedback when a command has no effect, for example when pressing the spacebar at the root level.

The property is either:

• a string, the name of an audio file in the soundsDirectory directory
• ‘none’ to turn off the sound

When true, the user cannot edit the mathfield.

remove-extraneous-parentheses: boolean
shared-virtual-keyboard-target-origin: string

Specify the targetOrigin parameter for postMessage to send control messages from child to parent frame to remote control of mathfield component.

Default: window.origin

smart-fence: boolean

When true and an open fence is entered via typedText() it will generate a contextually appropriate markup, for example using \left...\right if applicable.

When false, the literal value of the character will be inserted instead.

smart-mode: boolean

When true, during text input the field will switch automatically between ‘math’ and ‘text’ mode depending on what is typed and the context of the formula. If necessary, what was previously typed will be ‘fixed’ to account for the new info.

For example, when typing “if x >0”:

Type Interpretation
“i” math mode, imaginary unit
“if” text mode, english word “if”
“if x” all in text mode, maybe the next word is xylophone?
“if x >” “if” stays in text mode, but now “x >” is in math mode
“if x > 0” “if” in text mode, “x > 0” in math mode

Smart Mode is off by default.

Manually switching mode (by typing alt/option+=) will temporarily turn off smart mode.

Examples

• slope = rise/run
• If x > 0, then f(x) = sin(x)
• x^2 + sin (x) when x > 0
• When x<0, x^{2n+1}<0
• Graph x^2 -x+3 =0 for 0<=x<=5
• Divide by x-3 and then add x^2-1 to both sides
• Given g(x) = 4x – 3, when does g(x)=0?
• Let D be the set {(x,y)|0<=x<=1 and 0<=y<=x}
• \int_{the unit square} f(x,y) dx dy
• For all n in NN
smart-superscript: boolean

When true, when a digit is entered in an empty superscript, the cursor leaps automatically out of the superscript. This makes entry of common polynomials easier and faster. If entering other characters (for example “n+1”) the navigation out of the superscript must be done manually (by using the cursor keys or the spacebar to leap to the next insertion point).

When false, the navigation out of the superscript must always be done manually.

speech-engine: string
speech-engine-rate: string
speech-engine-voice: string
text-to-speech-markup: string
text-to-speech-rules: string
use-shared-virtual-keyboard: boolean

When true, use a shared virtual keyboard for all the mathfield elements in the page, even across iframes.

When setting this option to true, you must create the shared virtual keyboard in the the parent document:

import { makeSharedVirtualKeyboard } from 'mathlive';

makeSharedVirtualKeyboard({
virtualKeyboardToolbar: 'none',
});


Default: false

virtual-keyboard-layout: string
virtual-keyboard-mode: "auto" | "manual" | "onfocus" | "off"
• 'manual': pressing the virtual keyboard toggle button will show or hide the virtual keyboard. If hidden, the virtual keyboard is not shown when the field is focused until the toggle button is pressed.
• 'onfocus': the virtual keyboard will be displayed whenever the field is focused and hidden when the field loses focus. In that case, the virtual keyboard toggle button is not displayed.
• 'off': the virtual keyboard toggle button is not displayed, and the virtual keyboard is never triggered.

If the setting is empty, it will default to 'onfocus' on touch-capable devices and to 'off' otherwise.

virtual-keyboard-theme: string

The visual theme used for the virtual keyboard.

If empty, the theme will switch automatically based on the device it’s running on. The two supported themes are ‘material’ and ‘apple’ (the default).

virtual-keyboards: string

A space separated list of the keyboards that should be available. The keyboard 'all' is synonym with 'numeric', 'functions', ‘symbols’ 'roman' and 'greek',

The keyboards will be displayed in the order indicated.

Extends HTMLElement

Implements Mathfield

The MathfieldElement class provides special properties and methods to control the display and behavior of <math-field> elements.

It inherits many useful properties and methods from HTMLElement such as style, tabIndex, addEventListener(), getAttribute(), etc…

To create a new MathfieldElement:

// 1. Create a new MathfieldElement
const mfe = new MathfieldElement();
// 2. Attach it to the DOM
document.body.appendChild(mfe);


The MathfieldElement constructor has an optional argument of MathfieldOptions to configure the element. The options can also be modified later:

// Setting options during construction
const mfe = new MathfieldElement({smartFence: false});
// Modifying options after construction
mfe.setOptions({smartFence: true});


### CSS Variables

To customize the appearance of the mathfield, declare the following CSS variables (custom properties) in a ruleset that applied to the mathfield.

math-field {
--hue: 10       // Set the highlight color and caret to a reddish hue
}

CSS Variable Usage
--hue Hue of the highlight color and the caret
--highlight Color of the selection
--contains-highlight Backround property for items that contain the caret
--highlight-inactive Color of the selection, when the mathfield is not focused
--caret Color of the caret/insertion point
--primary Primary accent color, used for example in the virtual keyboard
--text-font-family The font stack used in text mode
--keyboard-zindex The z-index attribute of the virtual keyboard panel
--smart-fence-opacity Opacity of a smart gence (default is 50%)
--smart-fence-color Color of a smart fence (default is current color)

### CSS Parts

To style the virtual keyboard toggle, use the virtual-keyboard-toggle CSS part. To use it, define a CSS rule with a ::part() selector for example:

math-field::part(virtual-keyboard-toggle) {
color: red;
}


### Attributes

An attribute is a key-value pair set as part of the tag:

<math-field locale="fr"></math-field>


The supported attributes are listed in the table below with their correspnding property.

The property can be changed either directly on the MathfieldElement object, or using setOptions() if it is prefixed with options., for example

 getElementById('mf').value = '\\sin x';
getElementById('mf').setOptions({horizontalSpacingScale: 1.1});


The values of attributes and properties are reflected, which means you can change one or the other, for example:

getElementById('mf').setAttribute('virtual-keyboard-mode',  'manual');
console.log(getElementById('mf').getOption('virtualKeyboardMode'));
// Result: "manual"
getElementById('mf').setOptions({virtualKeyboardMode: 'onfocus');
console.log(getElementById('mf').getAttribute('virtual-keyboard-mode');
// Result: 'onfocus'


An exception is the value property, which is not reflected on the value attribute: the value attribute remains at its initial value.

Attribute Property
disabled disabled
default-mode options.defaultMode
fonts-directory options.fontsDirectory
sounds-directory options.soundsDirectory
horizontal-spacing-scale options.horizontalSpacingScale
inline-shortcut-timeout options.inlineShortcutTimeout

See MathfieldOptions for more details about these options.

In addition, the following global attributes can also be used:

• class
• data-*
• hidden
• id
• item*
• style
• tabindex

### Events

Listen to these events by using addEventListener(). For events with additional arguments, the arguments are availble in event.detail.

Event Name Description
input The value of the mathfield has been modified. This happens on almost every keystroke in the mathfield.
change The user has commited the value of the mathfield. This happens when the user presses Return or leaves the mathfield.
selection-change The selection (or caret position) in the mathfield has changed
mode-change The mode (math, text) of the mathfield has changed
undo-state-change The state of the undo stack has changed
read-aloud-status-change The status of a read aloud operation has changed
virtual-keyboard-toggle The visibility of the virtual keyboard panel has changed
blur The mathfield is losing focus
focus The mathfield is gaining focus
focus-out The user is navigating out of the mathfield, typically using the tab key
detail: {direction: ‘forward’
move-out The user has pressed an arrow key, but there is nowhere to go. This is an opportunity to change the focus to another element if desired.
detail: {direction: ‘forward’
math-error A parsing or configuration error happened
detail: ErrorListener<ParserErrorCode
keystroke The user typed a keystroke with a physical keyboard
detail: {keystroke: string, event: KeyboardEvent}
mount The element has been attached to the DOM
unmount The element is about to be removed from the DOM

To create programmatically a new mahfield use:

let mfe = new MathfieldElement();

// Set initial value and options mfe.value = “\frac{\sin(x)}{\cos(x)}”;

// Options can be set either as an attribute (for simple options)… mfe.setAttribute(‘virtual-keyboard-layout’, ‘dvorak’);

// … or using setOptions() mfe.setOptions({ virtualKeyboardMode: ‘manual’, });

// Attach the element to the DOM document.body.appendChild(mfe);

new MathfieldElement(options?: Partial<MathfieldOptions>): MathfieldElement
options: Partial<MathfieldOptions>
MathfieldElement

### Accessing and changing the content

value: string

The content of the mathfield as a Latex expression.

document.querySelector('mf').value = '\\frac{1}{\\pi}'


Updates the style (color, bold, italic, etc…) of the selection or sets the style to be applied to future input.

If there is no selection and no range is specified, the style will apply to the next character typed.

If a range is specified, the style is applied to the range, otherwise, if there is a selection, the style is applied to the selection.

If the operation is ‘toggle’ and the range already has this style, remove it. If the range has the style partially applied (i.e. only some sections), remove it from those sections, and apply it to the entire range.

If the operation is ‘set’, the style is applied to the range, whether it already has the style or not.

The default operation is ‘set’.

applyStyle(style: Style, options?: Range | {operation: "toggle" | "set"; range: Range}): void
style: Style
options:
• | Range

### module "mathfield-element"Types

The focus-out event signals that the mathfield has lost focus through keyboard navigation with the tab key.

The event detail.direction property indicates if tab (direction === "forward") or shift+tab (direction === “backward”) was pressed which can be useful to decide which element to focus next.

If the event is canceled by calling ev.preventDefault(), no change of focus will occur (but you can manually change the focus in your event handler: this gives you an opportunity to override the default behavior and selects which element should get the focus, or to prevent from a change of focus altogether).

If the event is not canceled, the default behavior will take place, which is to change the focus to the next/previous focusable element.

mfe.addEventListener('focus-out', (ev) => {
console.log("Losing focus ", ev.detail.direction);
});


direction: "forward" | "backward";

The keystroke event is fired when a keystroke is about to be procesed. The event is cancellable, which wills suprress further handling of the event.

event: KeyboardEvent;

The native keyboard event

keystroke: string;

A string descring the keystroke, for example “Alt-KeyU”. See W3C UIEvents for more information on the format of the descriptor.

The math-error custom event signals an error while parsing an expression.

document.getElementById('mf').addEventListener('math-error', (ev) => {
const err = ev.detail;
console.warn(err.code + (err.arg ? ': ' + err.arg : '') +
'\n%c|  ' + err.before + '%c' + err.after +
'\n%c|  ' + String(' ').repeat(err.before.length) +
'▲',
'font-weight: bold',
'font-weight: normal; color: rgba(160, 160, 160)',
'font-weight: bold; color: hsl(4deg, 90%, 50%)'
);
});


after: string;
arg: string;
before: string;
code: ParserErrorCode | MathfieldErrorCode;
latex: string;

The move-out event signals that the user pressed an arrow key but there was no navigation possible inside the mathfield.

This event provides an opportunity to handle this situation, for example by focusing an element adjacent to the mathfield.

If the event is canceled (i.e. evt.preventDefault() is called inside your event handler), the default behavior is to play a “plonk” sound.

direction: "forward" | "backward" | "upward" | "downward";

### module "options"Functions

Change the current physical keyboard layout.

Note that this affects some keybindings, but not general text input.

If set to auto the keyboard layout is guessed.

setKeyboardLayout(name: KeyboardLayoutName | "auto"): void
name:

Change the current physical keyboard layout to a layout that matches the specified locale, if one is available.

Note that this affects some keybindings, but not general text input.

setKeyboardLayoutLocale(locale: string): void
locale: string

These hooks provide an opportunity to intercept or modify an action. When their return value is a boolean, it indicates if the default handling should proceed.

onExport: (from: Mathfield, latex: string, range: Range): string

This hooks is invoked when the user has requested to export the content of the mathfield, for example when pressing ctrl/command+C.

This hook should return as a string what should be exported.

The range argument indicates which portion of the mathfield should be exported. It is not always equal to the current selection, but it can be used to export a format other than Latex.

By default this is:

 return \\begin{equation*}\${latex}\\end{equation*};

onKeystroke: (sender: Mathfield, keystroke: string, ev?: KeyboardEvent): boolean

A hook invoked when a keystroke is about to be processed.

• keystroke: a string describing the keystroke
• ev: the native keyboard event

Return false to stop the handling of the event.

#### deprecated

Use corresponding events of MathfieldEvent instead

onMoveOutOf: (sender: Mathfield, direction: "forward" | "backward" | "upward" | "downward"): boolean

A hook invoked when keyboard navigation would cause the insertion point to leave the mathfield.

• direction indicates the direction of the navigation, either "forward" or "backward" or "upward" or "downward".

Return false if the move has been handled by the hook.

Return true for the default behavior, which is playing a “plonk” sound.

#### deprecated

Use corresponding events of MathfieldEvent instead

onTabOutOf: (sender: Mathfield, direction: "forward" | "backward"): boolean

This hook is invoked when pressing tab (or shift-tab) would cause the insertion point to leave the mathfield.

direction indicates the direction of the navigation.

By default, the insertion point jumps to the next/previous focussable element.

#### deprecated

Use corresponding events of MathfieldEvent instead

The methods provide a notification that an event is about to occur or has occured.

In general instead of using this interface you should be listening to the corresponding event on MathfieldElement, i.e.

mfe.addEventListener('input', (ev) => {
console.log(ev.target.value);
});


#### deprecated

Use corresponding events of MathfieldEvent instead

onBlur: (sender: Mathfield): void

The mathfield has lost keyboard focus

onCommit: (sender: Mathfield): void
onContentDidChange: (sender: Mathfield): void
onContentWillChange: (sender: Mathfield): void
onFocus: (sender: Mathfield): void

The mathfield has gained keyboard focus

onModeChange: (sender: Mathfield, mode: ParseMode): void
onSelectionDidChange: (sender: Mathfield): void
onSelectionWillChange: (sender: Mathfield): void
onUndoStateDidChange: UndoStateChangeListener
onUndoStateWillChange: UndoStateChangeListener

tooltip?: string

aside: string

Markup displayed with the key label (for example to explain what the symbol of the key is)

• modifier: a modifier (shift/option, etc…) keycap
• small: display the label in a smaller size
• action: an “action” keycap (for arrows, return, etc…)
• separator w5: a half-width blank used as a separator. Other widths include w15 (1.5 width), w20 (double width) and w50 (five-wide, used for the space bar).
• bottom, left, right: alignment of the label
command: Selector | [Selector, ...any[]]

Command to perform when the keycap is pressed

content: string

HTML markup to represent the keycap.

This property is only useful when using a custom keycap shape or appearance. Usually, setting the label property is sufficient.

insert: string

Latex fragment to insert when the keycap is pressed (ignored if command is specified)

key: string

Key to insert when keycap is pressed (ignored if command, insert or latex is specified)

label: string

The HTML markup displayed for the keycap

### module "options"Types

createHTML: (html: string): any;

Support for Trusted Type.

This optional function will be called before a string of HTML is injected in the DOM, allowing that string to be sanitized according to a policy defined by the host.

fontsDirectory: string;

A URL fragment pointing to the directory containing the fonts necessary to render a formula.

These fonts are available in the /dist/fonts directory of the SDK.

Customize this value to reflect where you have copied these fonts, or to use the CDN version.

The default value is ‘./fonts’.

Changing this setting after the mathfield has been created will have no effect.

{
// Use the CDN version
fontsDirectory: ''
}

{
// Use a directory called 'fonts', located next to the
// mathlive.js (or mathlive.mjs) file.
fontsDirectory: './fonts'
}

{
// Use a directory located at the top your website
fontsDirectory: 'https://example.com/fonts'
}

soundsDirectory: string;

A URL fragment pointing to the directory containing the optional sounds used to provide feedback while typing.

Some default sounds are available in the /dist/sounds directory of the SDK.

mathModeSpace: string;

The Latex string to insert when the spacebar is pressed (on the physical or virtual keyboard). Empty by default. Use \; for a thick space, \: for a medium space, \, for a thin space.

When true, the user cannot edit the mathfield.

removeExtraneousParentheses: boolean;

If true, extra parentheses around a numerator or denominator are removed automatically.

scriptDepth: number | [number, number];

This option controls how many levels of subscript/superscript can be entered. For example, if scriptDepth is “1”, there can be one level of superscript or subscript. Attempting to enter a superscript while inside a superscript will be rejected. Setting a value of 0 will prevent entry of any superscript or subscript (but not limits for sum, integrals, etc…)

This can make it easier to enter equations that fit what’s expected for the domain where the mathfield is used.

To control the depth of superscript and subscript independently, provide an array: the first element indicate the maximum depth for subscript and the second element the depth of superscript. Thus, a value of [0, 1] would suppress the entry of subscripts, and allow one level of superscripts.

smartFence: boolean;

When true and an open fence is entered via typedText() it will generate a contextually appropriate markup, for example using \left...\right if applicable.

When false, the literal value of the character will be inserted instead.

smartMode: boolean;

When true, during text input the field will switch automatically between ‘math’ and ‘text’ mode depending on what is typed and the context of the formula. If necessary, what was previously typed will be ‘fixed’ to account for the new info.

For example, when typing “if x >0”:

Type Interpretation
“i” math mode, imaginary unit
“if” text mode, english word “if”
“if x” all in text mode, maybe the next word is xylophone?
“if x >” “if” stays in text mode, but now “x >” is in math mode
“if x > 0” “if” in text mode, “x > 0” in math mode

Smart Mode is off by default.

Manually switching mode (by typing alt/option+=) will temporarily turn off smart mode.

Examples

• slope = rise/run
• If x > 0, then f(x) = sin(x)
• x^2 + sin (x) when x > 0
• When x<0, x^{2n+1}<0
• Graph x^2 -x+3 =0 for 0<=x<=5
• Divide by x-3 and then add x^2-1 to both sides
• Given g(x) = 4x – 3, when does g(x)=0?
• Let D be the set {(x,y)|0<=x<=1 and 0<=y<=x}
• \int_{the unit square} f(x,y) dx dy
• For all n in NN
smartSuperscript: boolean;

When true, when a digit is entered in an empty superscript, the cursor leaps automatically out of the superscript. This makes entry of common polynomials easier and faster. If entering other characters (for example “n+1”) the navigation out of the superscript must be done manually (by using the cursor keys or the spacebar to leap to the next insertion point).

When false, the navigation out of the superscript must always be done manually.

An inline shortcut can be specified as a simple string or as an object literal with additional options:

    config.inlineShortcuts = {
half: '\\frac{1}{2}',
in: {
mode: 'math',
after: 'space+letter+digit+symbol+fence',
value: '\\in',
},
};


When using a string, the shortcut will apply in any mode, and regardless of the characters surrounding it.

When using an object literal the value key is required an indicate the shortcut substitution.

The mode key, if present, indicate which mode this shortcut will apply in, either 'math' or 'text'. If the key is not present the shortcut apply in all modes.

The 'after' key, if present, indicate in what context (surrounding characters) the shortcut will apply. One or more values can be specified, separated by a ‘|’ character. If any of the values match, the shortcut will be applicable.

Possible values are:

'space' A spacing command, such as \quad
'nothing' The begining of a group
'surd' A square root or n-th root
'frac' A fraction
'function' A function such as \sin or f
'letter' A letter, such as x or n
'digit' 0 through 9

inlineShortcutTimeout: number;

Maximum time, in milliseconds, between consecutive characters for them to be considered part of the same shortcut sequence.

A value of 0 is the same as infinity: any consecutive character will be candidate for an inline shortcut, regardless of the interval between this character and the previous one.

A value of 750 will indicate that the maximum interval between two characters to be considered part of the same inline shortcut sequence is 3/4 of a second.

This is useful to enter “±” as a sequence of two characters, while also supporting the “±” shortcut with the same sequence.

The first result can be entered by pausing slightly between the first and second character if this option is set to a value of 250 or so.

Note that some operations, such as clicking to change the selection, or losing the focus on the mathfield, will automatically timeout the shortcuts.

inlineShortcuts: Record<string, InlineShortcutDefinition>;

The keys of this object literal indicate the sequence of characters that will trigger an inline shortcut.

string | {after: string; mode: ParseMode; value: string}

A keybinding associates a combination of physical keyboard keys with a command.

For example:

{
"key": "cmd+a",
"command": "selectAll",
},
{
"key": 'ctrl+[Digit2]',
"ifMode": 'math',
"command": ['insert', '\\sqrt{#0}'],
}


command: Selector | [Selector, ...any[]];

The command is a single selector, or a selector with arguments

ifLayout: string[];
ifMode: ParseMode;

If specified, this indicates in which mode this keybinding will apply. If none is specified, the keybinding will apply in every mode.

ifPlatform: "macos" | "!macos" | "windows" | "!windows" | "linux" | "!linux" | "ios" | "!ios" | "android" | "!android" | "chromeos" | "!chromeos";

If specified, this indicates the OS platform to which this keybinding apply.

For example, if set to !macos this key binding will apply to every platform, except macOS.

key: string;

The pressed keys that will trigger this keybinding.

The key is made up of modifiers and the key itself.

The following modifiers can be used:

Platform Modifiers
macOS, iOS ctrl, shift, alt, cmd
Windows ctrl, shift, alt, win
Linux, Android, ChromeOS ctrl, shift, alt, meta

If the cmd modifier is used, the keybinding will only apply on macOS. If the win modifier is used, the keybinding will only apply to Windows. If the meta modifier is used, the keybinding will apply to platforms other than macOS or Windows.

The alt key is the option key on Apple keyboards.

The following values for keys can be used:

• az, 09
• , -, =, [, ], \, ;, ', ,, ., /
• left, up, right, down, pageup, pagedown, end, home
• tab, enter, escape, space, backspace, delete
• f1f19
• pausebreak, capslock, insert
• numpad0numpad9, numpad_multiply, numpad_add, numpad_separator
• numpad_subtract, numpad_decimal, numpad_divide

The values will be remapped based on the current keyboard layout. So, for example if a is used, on a French AZERTY keyboard the keybinding will be associated with the key labeled ‘A’ (event though it corresponds to the key labeled ‘Q’ on a US QWERTY keyboard).

To associate keybindings with physical keys independent of the keyboard layout, use the following keycodes:

• [KeyA][KeyZ], [Digit0][Digit9]
• [Backquote], [Minus], [Equal], [BracketLeft], [BracketRight], [Backslash], [Semicolon], [Quote], [Comma], [Period], [Slash]
• [ArrowLeft], [ArrowUp], [ArrowRight], [ArrowDown], [PageUp], [PageDown], [End], [Home]
• [Tab], [Enter], [Escape], [Space], [Backspace], [Delete]
• [F1][F19]
• [Pause], [CapsLock], [Insert]
• [Numpad0][Numpad9], [NumpadMultiply], [NumpadAdd], [NumpadComma]
• [NumpadSubtract], [NumpadDecimal], [NumpadDivide]

For example, using [KeyQ] will map to the the key labeled ‘Q’ on a QWERTY keyboard, and to the key labeled ‘A’ on an AZERTY keyboard.

As a general guideline, it is preferable to use the key values az for keybinding that are pseudo-mnemotechnic. For the other, it is generally preferable to use the keycodes.

Consider the key combination: alt+2. With an AZERTY (French) layout, the digits (i.e. ‘2’) are only accessible when shifted. The ‘2’ key produces ‘é’ when not shifted. It is therefore impossible on an AZERTY keyboard to produce the alt+2 key combination, at best it would be alt+shift+2. To indicate that the intended key combination should be alt and the key on the keyboard which has the position of the 2 key on a US keyboard, a key code should be used instead: alt+[Digit2]. This will correspond to a key combination that can be generated on any keyboard.

If a keybinding is invalid (impossible to produce or ambiguous) with the current keyboard layout, an error will be generated, and the onError listener will be called with a invalid-keybinding error code.

backgroundColorMap: (name: string): string | undefined;
colorMap: (name: string): string | undefined;

Map a color name as used in commands such as \textcolor{}{} or \colorbox{}{} to a CSS color value.

Use this option to override the standard mapping of colors such as “yellow” or “red”.

If the name is not one you expected, return undefined and the default color mapping will be applied.

If a backgroundColorMap() function is not provided, the colorMap() function will be used instead.

If colorMap() is not provided, default color mappings are applied.

The following color names have been optimized for a legible foreground and background values, and are recommended:

• red, orange, yellow, lime, green, teal, blue, indigo, purple, magenta, black, dark-grey, grey, light-grey, white
defaultMode: "inline-math" | "math" | "text";

The mode of the element when it is empty:

• 'math': equivalent to \displaystyle (display math mode)
• 'inline-math': equivalent to \inlinestyle (inline math mode)
• 'text': text mode
horizontalSpacingScale: number;
deprecated

Scaling factor to be applied to horizontal spacing between elements of the formula. A value greater than 1.0 can be used to improve the legibility.

#### deprecated

Use registers \thinmuskip, \medmuskip and \thickmuskip

letterShapeStyle: "auto" | "tex" | "iso" | "french" | "upright";

Control the letter shape style:

letterShapeStyle xyz ABC αβɣ ΓΔΘ
iso it it it it
tex it it it up
french it up up up
upright up up up up

(it) = italic (up) = upright

The default letter shape style is auto, which indicates that french should be used if the locale is “french”, and tex otherwise.

#### Historical Note

Where do the “french” rules come from? The TeX standard font, Computer Modern, is based on Monotype 155M, itself based on the Porson greek font which was one of the most widely used Greek fonts in english-speaking countries. This font had upright capitals, but slanted lowercase. In France, the traditional font for greek was Didot, which has both upright capitals and lowercase.

As for roman uppercase, they are recommended by “Lexique des règles typographiques en usage à l’Imprimerie Nationale”. It should be noted that this convention is not universally followed.

macros: MacroDictionary;

A dictionary of LaTeX macros to be used to interpret and render the content.

For example, to add a new macro to the default macro dictionary:

mf.setConfig({
macros: {
...mf.getOption('macros'),
smallfrac: '^{#1}\\!\\!/\\!_{#2}',
},
});


Note that getOption() is called to keep the existing macros and add to them. Otherwise, all the macros are replaced with the new definition.

The code above will support the following notation:

\smallfrac{5}{16}

registers: Registers;

LaTeX global registers override.

locale: string;

The locale (language + region) to use for string localization.

If none is provided, the locale of the browser is used.

strings: Record<string, Record<string, string>>;

Example

{
"fr-CA": {
"tooltip.undo": "Annuler",
"tooltip.redo": "Refaire",
}
}

When a key on the virtual keyboard is pressed, produce a short audio feedback.

If the property is set to a string or HTMLAudioElement, the same sound is played in all cases. Otherwise, a distinct sound is played:

• delete a sound played when the delete key is pressed
• return … when the return/tab key is pressed
• spacebar … when the spacebar is pressed
• default … when any other key is pressed. This key is required, the others are optional. If they are missing, this sound is played as well.

The value of the properties should be either a string, the name of an audio file in the soundsDirectory directory, an HTMLAudioElement or null to supress the sound.

keypressVibration: boolean;

When a key on the virtual keyboard is pressed, produce a short haptic feedback, if the device supports it.

Sound played to provide feedback when a command has no effect, for example when pressing the spacebar at the root level.

The property is either:

• a string, the name of an audio file in the soundsDirectory directory
• an HTMLAudioElement
• null to turn off the sound
virtualKeyboardContainer: "null" | HTMLElement;

Element the virtual keyboard element gets appended to. The position attribute of this element should be relative so that the virtual keyboard can correctly be placed relative to this element.

When using full screen elements that contain mathfield, set this property to the full screen element to ensure the virtual keyboard will be visible.

Default: document.body

A range is said to be collapsed when start and end are equal. When specifying a range, a negative offset can be used to indicate an offset from the last valid offset, i.e. -1 is the last valid offset, -2 is one offset before that, etc… A normalized range will always be such that start <= end, start >= 0, end >= 0, start < lastOffset, end < lastOffset. All the methods return a normalized range. See Also [start: Offset, end: Offset] ### module "mathfield"ReplacementFunction Permalink (args: {latex: string; match: string; p: string[]; range: Range}): string ### module "mathfield"Selection Permalink A selection is a set of ranges (to support discontinous selection, for example when selecting a column in a matrix). If there is a single range and that range is collapsed, the selection is collapsed. A selection can also have a direction. While many operations are insensitive to the direction, a few are. For example, when selecting a fragment of an expression from left to right, the direction of this range will be “forward”. Pressing the left arrow key will sets the insertion at the start of the range. Conversely, if the selectionis made from right to left, the direction is “backward” and pressing the left arrow key will set the insertion point at the end of the range. See Also direction: "forward" | "backward" | "none"; ranges: Range[]; ## module "commands" Permalink ## module "commands"interface Commands Permalink Commands return true if they resulted in a dirty

TeX registers represent ‘variables’ and ‘constants’.

Changing the values of some registers can modify the layout of math expressions.

The following registers might be of interest:

• thinmuskip
• medmuskip
• thickmuskip
• nulldelimiterspace
• delimitershortfall
• jot

Variants indicate a stylistic alternate for some characters.

Typically, those are controlled with explicit commands, such as \mathbb{} or \mathfrak{}. This type is used with the applyStyle method to change the styling of a range of selected characters.

In mathematical notation these variants are used not only for visual presentation, but they may have semantic significance.

For example, the set ℂ should not be confused with the physical unit 𝖢 (Coulomb).

When rendered, these variants can map to some built-in fonts. Latex supports a limited set of characters. However, MathLive will map characters not supported by Latex fonts(double-stuck variant for digits for example) to a Unicode character (see Mathematical Alphanumeric Symbols on Wikipedia ).

normal is a synthetic variant that maps either to main (roman) or math (italic) depending on the symbol and the letterShapeStyle.

The math variant has italic characters as well as slightly different letter shape and spacing (a bit more space after the “f” for example), so it’s not completely equivalent to a main variant with italic variant style applied.

• | "monospace"
• | "normal"
• | "main"
• | "math"

Some variants support stylistic variations.

Note that these stylistic variations support a limited set of characters, typically just uppercase and lowercase letters, and digits 0-9 in some cases.
