Vscode-neovim: Investigate if it's possible to make jj work

[asvetliakov]

The idea is to not listen in insert mode, but rather bind j to some handler. Then run timer - if same command was pressed within timer's timeout - call escape, if not - insert j (alternatively insert j immediately, then remove if needed).

This won't work for jk but can be good compromise

@asvetliakov This is the same technique I use in my Vim-everywhere plugin for Mac.

It's unfortunate you cannot watch all the keys at once though. If you _can_ watch all the keys then you can deal with it in the same manner I did:

Another 3rd-party possibility for people is to figure out how use something like Karabiner to bind a sequence like jk to fire something out of keyboard range like F20, then bind F20 to Vim mode:

The VSCode Vim extension does insert a character and then removes it if a chord is pressed. Might be something to look into.

@dbalatero , @satvikpendem Thank you for suggestions

fresh!

Is it possible to configure the keys directly? I'd like to use fd instead, looks like you use the variable vscode-neovim.compositeEscape1/2, might be good to make them user configurable.

Edit: just reread the README, looks like it is configurable. Thanks!
