If you want to completely swap caps lock and escape, you have to replace the
"Lock" on caps lock. Drop this file in your home directory(don't copy the start&end lines!!):
-----------start------------
! Swap caps lock and escape
remove Lock = Caps_Lock
keysym Escape = Caps_Lock
keysym Caps_Lock = Escape
add Lock = Caps_Lock
------------end-------------
and call it ".speedswapper". Then open a terminal and type
$ xmodmap .speedswapper
and you'll be twice as efficient in vim.
Who needs caps lock anyway?
