###Dollarify (`$`)
 - Encloses selection in `$...$`
 - Enabled on all supported sites
 - Keyboard shortcut: <kbd>Alt</kbd>-<kbd>M</kbd>

###Double Dollarify (`$$`)
 - Encloses selection in `$$...$$`
 - Enabled on all supported sites
 - Keyboard shortcut: _None_ (use <kbd>Alt</kbd>-<kbd>M</kbd> twice, that should do the trick). Exception: <kbd>Alt</kbd>-<kbd>D</kbd> on electronics.SE

###Exit math mode

 - Finds the next dollar symbol and puts the cursor ahead of it. Useful to keep the flow of typing.
