As I’ve said before, my Caps Lock key serves as both my Left Control key (if I hold it), and my Escape key (if I tap it).
This configuration has a bug: occasionally entering
Esc when I want an empty
Left Ctrl. Essentially, when I hold down on the key and then let go without
tapping any other key, the expected behaviour is
that it should behave like tapping a
Left Ctrl. The actual behaviour is that
Esc, which is not the greatest key to accidentally tap.
I’ve talked about the plugin in the post about trying to setup home row mods.
Install interception-tools and dual function keys. The installation process
is available at the links; for Arch systems you can run
sudo pacman -Syu interception-tools interception-dual-function-keys.
Then, configuration. Setup the following job in
- JOB: "intercept -g $DEVNODE | dual-function-keys -c path_to_config.yaml | uinput -d $DEVNODE" DEVICE: EVENTS: EV_KEY: [KEY_CAPSLOCK, KEY_ESC]
The config can be setup wherever is appropriate.
TIMING: - TAP_MILLISEC: 200 - DOUBLE_TAP_MILLISEC: 0 MAPPINGS: - KEY: KEY_CAPSLOCK TAP: KEY_ESC HOLD: KEY_LEFTCTRL - KEY: KEY_ESC TAP: KEY_ESC HOLD: KEY_CAPSLOCK
Generally, caveats as mentioned in the home row mods post apply. The key details are to ensure that
TIMING: ... MAPPINGS: # Enter your other mappings - KEY: KEY_CAPSLOCK ...
