I just swapped Backspace and CapsLock by adding 'caps:backspace' to the xkb-options in dconf-editor. It works, but Backspace is not repeatable now, it only deletes one char and stops. How can I fix this?
I've read this.
xmodmap -e "clear Lock"
The creator of the thread had mentioned this in an edit and it worked for me. I am unable to understand how this works exactly but it works.
