Swap modifiers to previous assignment because I don't want to fix them in
~/.fvwm. Assign keycode to Caps_Lock before aliasing to LCtrl so ~/.xmodmaprc
script can be re-evaluated without errors.
! To load this config run:
! $ xmodmap .xmodmaprc
keycode 133 = Super_L
keycode 134 = Hyper_L
! keycode 135 = Menu
clear mod3
clear mod4
add mod3 = Super_L
add mod4 = Hyper_L
! Delete CapsLock (map to Ctrl).
clear Lock
clear Control
keycode 66 = Caps_Lock
keysym Caps_Lock = Control_L
add Control = Control_L Control_R
