Theia Editor Key Bindings switching (Default, VI, Emacs)

Provide ability for changing editor Key Bindings (Default, VI, Emacs)

[RomanNikitenko]

the plugin with Emacs key bindings is temporarily placed here

Corresponding to this comment Theia does not support chord keybindings properly at the moment, so keybindings for actions like 'Delete blank lines around'(Ctrl+X Ctrl+O) or 'Select All'(Ctrl+X H) are not implemented.
Update: as it turned out, Theia has ability to handle chord keybindings, so I added a few these ones like: Jump to line, Add selection to next find match, QuickOpen a file and so on. Implemented Key Bindings for Emacs you can see here

depends on eclipse-theia/theia#2783

Can you share update on the plans for introducing VI bindings?

[RomanNikitenko]

Our first attempt to provide VI and Emacs key bindings was providing own extensions.
Some set of key bindings was implemented within this work.

At some stage of our project development we decided to change approach and invest our efforts for vs code extensions support - it allows to use existed extensions/plugins.
So the work on the issue was stopped till plugin API is aligned with vs code, vs code format of context is supported, sections from package.json of an extensions is used, commands Id is aligned with vs code commands and so on.

I tried to turn on VI and Emacs vs code extensions for theia a few days ago. Looks like theia picks up the key bindings from the extensions

But there are still a lot of conflicts:

and I guess we have other incompatibilities.

Unfortunately it still works incorrectly, so something is missing, we should investigate it and define what we need to align with vs code to support these extensions.

Thank you for the update! Having support for VS Code key binding extensions sounds like very good long term decision. Looking forward!
