I found out this particular file which can defined behavior of brackets, etc, in a specific language: https://code.visualstudio.com/api/language-extensions/language-configuration-guide
I would like to simply configure the addition of '$' before and after selected text in LaTeX documents, using for example 'alt+$' keybinding.
So far, it's not clear to me how to do that, even with the documentation pages I stumbled upon. (https://code.visualstudio.com/api/references/contribution-points#contributeslanguages for example).
I would think that you could simply do that in keybindings.json but it appears you can't (or I don't know how). Any idea?
