The dialog boxes in MathJax are movable and sizeable.

\n\n

For mouse users, dragging any of the edges will enlarge or shrink\n the dialog box by moving that side. Dragging any of the corners\n changes the two sides that meet at that corner. Dragging elsewhere on\n the dialog frame will move the dialog without changing its size.

\n\n

For keyboard users, there are two ways to adjust the position\n and size of the dialog box. The first is to hold the\n Alt or Option key and press any of the arrow\n keys to move the dialog box in the given direction. Hold the\n Win or Command key and press any of the\n arrow keys to enlarge or shrink the dialog box. Left and right\n move the right-hand edge of the dialog, while up and down move the\n bottom edge of the dialog.\n

\n\n

For some users, holding two keys down at once may be difficult,\n so the second way is to press the m to start "move"\n mode, then use the arrow keys to move the dialog box in the given\n direction. Press m again to stop moving the dialog.\n Similarly, press s to start and stop "sizing" mode,\n where the arrows will change the size of the dialog box.

\n\n

Holding a shift key along with the arrow key will\n make larger changes in the size or position, for either method\n described above.

\n\n

Use Tab to move among the text, buttons, and links\n within the dialog. The Enter or Space key\n activates the focused item. The Escape key closes the\n dialog, as does clicking outside the dialog box, or clicking the\n "\xd7" icon in the upper right-hand corner of the dialog.

","

Browsers: MathJax works with all modern browsers including"," Edge, Firefox, Chrome, Safari, Opera, and most mobile browsers.

","

Math Menu: MathJax adds a contextual menu to equations."," Right-click or CTRL-click on any mathematics to access the menu.

",'
',"

Show Math As: These options allow you to view the formula's"," source markup (as MathML or in its original format).

","

Copy to Clipboard: These options copy the formula's source markup,"," as MathML or in its original format, to the clipboard"," (in browsers that support that).

","

Math Settings: These give you control over features of MathJax,"," such the size of the mathematics, the mechanism used to display equations,"," how to handle equations that are too wide, and the language to use for"," MathJax's menus and error messages (not yet implemented in v4).","

","

Accessibility: MathJax can work with screen"," readers to make mathematics accessible to the visually impaired."," Turn on speech or braille generation to enable creation of speech strings"," and the ability to investigate expressions interactively. You can control"," the style of the explorer in its menu.

","
","

Math Zoom: If you are having difficulty reading an"," equation, MathJax can enlarge it to help you see it better, or"," you can scale all the math on the page to make it larger."," Turn these features on in the Math Settings menu.

","

Preferences: MathJax uses your browser's localStorage database"," to save the preferences set via this menu locally in your browser. These"," are not used to track you, and are not transferred or used remotely by"," MathJax in any way.

Exploring expressions ${t}

\n\n

The mathematics on this page is being rendered by MathJax, which\n generates both the text spoken by screen readers, as well as the\n visual layout for sighted users.

\n\n

Expressions typeset by MathJax can be explored interactively, and\n are focusable. You can use the Tab key to move to a typeset\n expression${e}. Initially, the expression will be read in full,\n but you can use the following keys to explore the expression\n further:

\n\n
    \n\n
  • Down Arrow moves one level deeper into the\n expression to allow you to explore the current subexpression term by\n term.
    • \n\n
  • Up Arrow moves back up a level within the\n expression.
    • \n\n
  • Right Arrow moves to the next term in the\n current subexpression.
    • \n\n
  • Left Arrow moves to the next term in the\n current subexpression.
    • \n\n
  • Shift+Arrow moves to a\n neighboring cell within a table.
    • \n\n
  • 0-9+0-9 jumps to a cell\n by its index in the table, where 0 = 10.
    • \n\n
  • Home takes you to the top of the\n expression.
    • \n\n
  • Enter or Return clicks a\n link or activates an active subexpression.
    • \n\n
  • Space opens the MathJax contextual menu\n where you can view or copy the source format of the expression, or\n modify MathJax's settings.
    • \n\n
  • Escape exits the expression\n explorer.
    • \n\n
  • x gives a summary of the current\n subexpression.
    • \n\n
  • z gives the full text of a collapsed\n expression.
    • \n\n
  • d gives the current depth within the\n expression.
    • \n\n
  • s starts or stops auto-voicing with\n synchronized highlighting.
    • \n\n
  • v marks the current position in the\n expression.
    • \n\n
  • p cycles through the marked positions in\n the expression.
    • \n\n
  • u clears all marked positions and returns\n to the starting position.
    • \n\n
  • > cycles through the available speech\n rule sets (MathSpeak, ClearSpeak).
    • \n\n
  • < cycles through the verbosity levels\n for the current rule set.
    • \n\n
  • b toggles whether Braille notation is combined\n with speech text for tactile Braille devices, as discussed\n below.\n\n
  • h produces this help listing.
    • \n
\n\n

The MathJax contextual menu allows you to enable or disable speech\n or Braille generation for mathematical expressions, the language to\n use for the spoken mathematics, and other features of MathJax. In\n particular, the Explorer submenu allows you to specify how the\n mathematics should be identified in the page (e.g., by saying "math"\n when the expression is spoken), and whether or not to include a\n message about the letter "h" bringing up this dialog box. Turning off\n speech and Braille will disable the expression explorer, its\n highlighting, and its help icon.

\n\n

Support for tactile Braille devices varies across screen readers,\n browsers, and operative systems. If you are using a Braille output\n device, you may need to select the "Combine with Speech" option in the\n contextual menu's Braille submenu in order to obtain Nemeth or Euro\n Braille output rather than the speech text on your Braille\n device. ${s}

\n\n

The contextual menu also provides options for viewing or copying a\n MathML version of the expression or its original source format,\n creating an SVG version of the expression, and viewing various other\n information.

\n\n

Finally, selecting the "Insert Hidden MathML" item from the options\n submenu will turn of MathJax's speech and Braille generation and\n instead use visually hidden MathML that some screen readers can voice,\n though support for this is not universal across all screen readers and\n operating systems. Selecting speech or Braille generation in their\n submenus will remove the hidden MathML again.

\n\n
