About

This userscript gives users some quick key bindings to speed up the process of editing mathjax/chem/etc. into posts.

Example usage: (the hotkeys are customizable!)

1. Pressing Alt+Shift+P would insert \pi directly.
2. Pressing Alt+R would insert \mathrm{} with the caret auto-placed in the middle. Pressing Alt-R again would unwrap the \mathrm{} back.
3. Pressing Alt+R with some text pre-selected would insert \mathrm{text}, retaining the selection on the text. Pressing Alt-R again would unwrap the \mathrm{text} back to text, retaining the selection on text.
4. Prepending Ctrl to any of the above keybindings will auto-surround the insertion text with $$ (or \$ on some other SE sites)
5. The keybinding and its associated insertion text can be modified by the user. So, you can set it to insert \pi on Alt+A instead.

Moreover, there are certain reserved keycodes like:

• Alt-Z => dollar-ifying (text => $text$)
• Alt-C => double dollar-ifying (text => $$text$$)
• Alt-A => frac-ify (A/B => \frac{A}{B})
• Alt-S => align-ify (image demo)

You can still change their keycode or entirely disable them as well, the given Z/C/A/etc. keycombos are just the default values. Read more on the GitHub page.
