Why? Well, because as an emacs user, you are probably tired of your pinky trip to ctrl in order to do the “chords”.
I would assume, hypothetical reader, that you have already tried changing caps for ctrl. Well that’s nice, however, let me introduce you the better idea (giving credit where is due, thanks for this Umgeher!).
It is a lot more comfortable and an easier transition to change
caps->shift. The muscle memory for shift stays the same and ctrl is in a much more comfortable position. Here is
xmodmap script to arrange that:
! making shift ctrl and caps shift remove Lock = Caps_Lock remove Shift = Shift_L remove Control = Control_L keysym Caps_Lock = Shift_L keysym Shift_L = Control_L keysym Control_L = Control_L add Lock = Caps_Lock add Shift = Shift_L add Control = Control_L
