I am kind of obsessed with keyboard shortcuts, ever since discovering Vim a million years ago. The Vim shortcuts are burned into my brain.

I've found that that itch is pretty much entirely solved by Sway (especially since it supports modal navigation, which I have become pretty addicted to), but honestly I actually found Gnome Shell (as of about ~2 years ago) pretty keyboard friendly. Hitting the Windows key [1] brings up the global search and that worked to launch stuff, moving between workspaces worked ok. I know it's popular to hate on Gnome 3 and beyond but honestly I rather liked it.

[1] Or whatever the official name for it is; it's a Windows logo on my keyboard.
