“Caps Lock” is by far the most useless, stupid, shity and annoying key on a keyboard.

Fortunately, it can be totaly disabled on Linux X environment using Option "XkbOptions" "ctrl:nocaps".

File /etc/X11/xorg.conf.d/00-keyboard.conf :

1
2
3

5

Section "InputClass"
        Identifier "system-keyboard"
        MatchIsKeyboard "on"
        Option "XkbOptions" "ctrl:nocaps"
EndSection

If you’re on Windows, well… you have bigger problems anyway.
