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 ] };
