Usage

You can see the extension settings popup by clicking on its icon.

Example settings:

https://leanprover.zulipchat.com
https://github.com/leanprover-community/mathlib

With the settings above, whenever you type in \a and then hit space, the extension will replace \a by α.

This behavior is only triggered in pages whose URLs start with the strings listed in the URL matches field.

The ON by default option allows you to configure the extension to be active or inactive when you visit those pages.

Hitting ALT twice switches the extension state between active and inactive. You should see the extension icon changing colors if you're visiting a page listed in the URLs field.
