'''Mouse keys''' is a feature of some [[graphical user interface]]s that uses the keyboard (especially [[numeric keypad]])
This is a preview for the new '''MathML rendering mode''' (with SVG fallback), which is availble in production for registered users.
as a [[pointing device]] (usually replacing a [[Computer mouse|mouse]]). Its roots lie in the earliest days of [[visual editor]]s when line and column navigation was controlled with [[arrow keys]] (e.g., [[HJKL keys|hjkl]], [[ESDX|ctl-esdx]]).
Today, mouse keys usually refers to the [[numeric keypad]] layout standardized with the introduction of the [[X Window System]] in 1984.<ref>[http://www.xfree86.org/current/XKBproto.pdf The X Keyboard Extension: Protocol Specification]</ref><ref>[http://www.xfree86.org/current/XKBlib.pdf The X Keyboard Extension: Library Specification]</ref>


==Layout==
If you would like use the '''MathML''' rendering mode, you need a wikipedia user account that can be registered here [[https://en.wikipedia.org/wiki/Special:UserLogin/signup]]

==History==
'''MathML'''
Historically, MouseKeys supported GUI programs when many [[Computer terminal#Graphical terminals|terminal]]s had no dedicated [[pointing device]]. As pointing devices became ubiquitous, the use of mouse keys narrowed to situations where a pointing device was missing, unusable, or inconvenient. Such situations may arise from the following:
:<math forcemathmode="mathml">E=mc^2</math>
*precision requirements (e.g., [[technical drawing]])
*[[accessibility|disabled user]] or ergonomics issues
*environmental limits (e.g., vibration in car or plane)
*broken equipment

This is a preview for the new MathML rendering mode (with SVG fallback), which is availble in production for registered users.

If you would like use the MathML rendering mode, you need a wikipedia user account that can be registered here [[1]]

  • Only registered users will be able to execute this rendering mode.
  • Note: you need not enter a email address (nor any other private information). Please do not use a password that you use elsewhere.

Registered users will be able to choose between the following three rendering modes:

MathML


Follow this link to change your Math rendering settings. You can also add a Custom CSS to force the MathML/SVG rendering or select different font families. See these examples.

Demos

Here are some demos:
