Add keyboard shortcut for toggling math environment

[yfzhao20]

I usually use ctrl + M shortcut in VS Code or Alt + = in MS Word to insert math block. It may be more convenient if keybindings for toggling math environment (e.g.: ctrl + M inserts $$...$$) are supported in Obsidian LaTeX suite😉

This! I don't know if there's a way to use a keyboard shortcut as trigger, but that would be a useful feature, more convenient and less prone to problems while writing normal text, in my opinion.
