I’ve never found the Caps Lock key very useful. Besides never using it, it takes a very large space in a particularly easy-to-reach region of the keyboard (next to my left pinky). It seems like Google shares my opinion. Ever since I’ve gotten my Acer C720, I’ve noticed how useful would be to have the Super key (aka Windows key) more easily accessible to my fingers.
Then I decided to map the Caps Lock key as a Super key. It didn’t take long for me to find that this mapping is so common that a single short command can be used to do it:
setxkbmap -option caps:super
There, easy enough. But there are other ways to do this. The one I ended up using is to use dconf-editor to set this modifier as default in GNOME. The key name is org.gnome.desktop.input-sources.xkb-options. Just add [‘caps:super’] and you’ll be set.
