I like using emacs-style navigation in the terminal (e.g. Ctrl + N for down, Ctrl +P for up, Ctrl + A for home, Ctrl + E for end), and I want to do something similar for navigation elsewhere. I would like to use CapsLock + N/P/A/E/etc for down/up/home/end in all apps (I previously used the AutoHotkey script at https://github.com/usuyama/emacs-like-key-bindings-windows to accomplish this in Windows).
I’m currently using KDE Plasma on Wayland, and I haven’t seen anything obvious to do this while poking around settings. Any suggestions? Thank you in advance!
Check out kmonad. You can set on-hold caps to switch to an Emacs navigation layer. In that layer you can for example set the n button to send the arrow instead.
It complains in Wayland about using some X11 tool, but works without issues from my limited experience.
