<!-- Excerpt: Mathjax Buttons adds convenient buttons and keyboard shortcuts for those who use MathJax on SE -->

Adds some math/science buttons to the editor on science SE sites. These buttons are useful for converting selected text to math, formatting SI units, and formatting chemical equations. **There are also keyboard shortcuts for them**, which are IMO more useful than the buttons themselves.

(The SI units and chem buttons are only enabled on certain sites)

Currently, it runs on the SE sites listed [on the site matrix here][1].


There also is an **exit-inline-math-mode hotkey** (<kbd>Alt</kbd>-<kbd>Z</kbd>). This one moves the cursor just after the next instance  of `$`. It's useful if you want to keep the flow of typing. For example, on Chem.SE, formatting H<sub>2</sub>O becomes <kbd>Alt</kbd>-<kbd>C</kbd>+`type H2O`+<kbd>Alt</kbd>-<kbd>Z</kbd> and you can immediately continue typing(no need to rightarrow-out of math mode). On CStheory/CS, typing "I like NP-complete problems!", where "NP" is sansserif, becomes: `type 'I like' `+<kbd>Alt</kbd>-<kbd>S</kbd>+`type NP`+<kbd>Alt</kbd>-<kbd>Z</kbd>+`type '-complete problems!'`. Once you're used to the shortcut, typing math fluidly becomes much easier!



**If you want your mathjax-enabled SE site to be supported, please let me know!**


My long term goal is to make [this script][2] a part of it (I'm still working on that script, though--so it will be a while)

###chem-ify (`O`<sub>`2`</sub>)
 - Encloses selection in `$\ce{...}$` (mhchem chemical equation formatter)
 - Use the `$` button on the `\ce`'d text to make this a block element (use <kbd>Alt</kbd>-<kbd>M</kbd>)
