SketchyVim VS GIMX

However, I do look for projects that embed vim in other applications. Stuff like https://github.com/glacambre/firenvim, https://github.com/FelixKratz/SketchyVim, and the deceased https://www.onivim.io all embed real, actual (Neo)vim in text input fields and it just feels right

if you're on macOS, there's SketchyVim

there's a free, open source project that brings a Vim backend engine to macOS: https://github.com/FelixKratz/SketchyVim currently it's using libvim but a neovim port should be possible. the issue though using a Vim backend is that it's not adapted to macOS' buffer. so it will work only 1) if the text is readable and writable 2) moves like zz, L, etc. that play with screen buffers will not work.

With this nifty utility https://github.com/FelixKratz/SketchyVim you can use the power of vim in Safari, in Finder search boxes and a multitude of other places in macOS. It works by using a real vim buffer in the backend and synchronizing it with the system text fields via the accessibility API. It is super light weight and all vim text features are supported. If you enjoy vim as much as I do this utility might be worth a try.

That scratchpad idea with a global hotkey sounds like a solution that could work. I haven't tried it, but isn't that similar (functionality-wise) to https://github.com/FelixKratz/SketchyVim?

There is a much more capable open source version of this: https://github.com/FelixKratz/SketchyVim

I found this very powerful tool which enables vim bindings in most macOS text boxes: https://github.com/FelixKratz/SketchyVim. It is a

A second option would be to ask GIMX developers to make a snap package, if possible. Converting .deb packages to snap packages is supposedly easy and without problems.
