To be honest I'm not sure or what I want is possible but it would be very nice if this can be done.
I changed the behavior of the Capslock to act like a Ctrl key. Now it's just an Ctrl key only positioned at an easier to reach place, which is great, but…
It would even be nicer if I could press the Capslock key followed by a second key press. I mean for example: Capslock(ctrl) → V instead of the normal Capslock(ctrl) + V.
I guess what I'm looking for is a somewhat similar behavior as the G(go) combinations in Vim or Gmail. Does anyone have an idea how this can be accomplished?
Don't know how to arrange the second bit of behaviour. Doing the following should set you up for simply making Capslock act like the Ctrl key.
If you would prefer to launch this from the terminal, you can do so by running the terminal command
gnome-control-center
. This should bring up a window titled "system settings". You should see several icons, one of which is "Keyboard Layout". Its under the "personal" heading. Once you select it, you can follow the above steps.
