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!

EDIT: I was able to do what I want with evremap. The crux of the config is:

[[dual_role]]
input = "KEY_CAPSLOCK"
hold = ["KEY_F19"]
tap = ["KEY_ESC"]

[[remap]]
input = ["KEY_F19", "KEY_N"]
output = ["KEY_DOWN"]

[[remap]]
input = ["KEY_F19", "KEY_P"]
output = ["KEY_UP"]

See my reply below for more info.

      Looks like evremap will do what I want, plus a nifty bonus! The following config lets me use CapsLock + N/P/etc to navigate. And if I just tap CapsLock without pressing anything else, it will act as escape.

      device_name = "Telink Wireless Receiver"

[[dual_role]]
input = "KEY_CAPSLOCK"
hold = ["KEY_F19"]
tap = ["KEY_ESC"]

[[remap]]
input = ["KEY_F19", "KEY_N"]
output = ["KEY_DOWN"]

[[remap]]
input = ["KEY_F19", "KEY_P"]
output = ["KEY_UP"]

[[remap]]
input = ["KEY_F19", "KEY_B"]
output = ["KEY_LEFT"]

[[remap]]
input = ["KEY_F19", "KEY_F"]
output = ["KEY_RIGHT"]

[[remap]]
input = ["KEY_F19", "KEY_A"]
output = ["KEY_HOME"]

[[remap]]
input = ["KEY_F19", "KEY_E"]
output = ["KEY_END"]

      Note: I used F19 because it doesn’t seem to be bound to anything by default. Apparently, a bunch of the other function keys already did things, as described in /usr/share/X11/xkb/symbols/inet

      $ cat /usr/share/X11/xkb/symbols/inet | grep FK13
    key    {      [ XF86Tools         ]       };
    key   {       [ XF86MailForward       ]       };
    key   {       [ XF86Word              ]       };      // F2
    key   {       [ XF86MailForward       ]       };      // F3

$ cat /usr/share/X11/xkb/symbols/inet | grep FK20
    key    {      [ XF86AudioMicMute      ]       };
