[FR] Support for the VIM Key Bindings / Mode

[StefanoRausch]

I use the VIM mode (VIM) on my laptop and iPad with a physical keyboard. It is such a godsend.

Unfortunately, CssE does not support VIM. It is so strange to switch back to the old ways of editing a file / note.

Do you have plans to add this functionality? It would be awesome!

Definitely! I'm hoping it'll be as easy as reusing the Codemirror extension Obsidian is using.

Should have time in the next couple of weeks to look into this, I'll be on vacation next week so it'll be at least a week.

Fantastic and thanks!

Enjoy your vacation. 😎

Thank you, Zachatoo!

Let me know how this works for you! I only know a few vim bindings since I don't use vim very often, but the bindings I tried appeared to work. Feel free to reopen this issue or create a new issue if there's specific bindings that don't appear to work that would be expected of most/all vim editors and I can give it a look, could easily be accidentally overriding vim keybinds with other keybinds.

For an initial release, it works well -- thank you so much!

I have noticed the following:

• The ESCAPE key exits the insert mode when your work only with one tab containing the CSS snippet. Otherwise, it switches to the left (main target) or the right tab (if the left one does not exist) instead. Returning to the snippet tab results in being back to the normal mode. Can you improve the user experience?

• The Vimrc Support plugin is not supported. I.e., my personal key bindings are not recognised. It is not a dealbreaker, but it would be fantastic if you could "fine-tune" the user experience here too.

To state it again: A great first implementation!
