[vox-tech] using xmodmap to swap modifier key locations

[Shawn P. Neugebauer]

Pete alluded to, but did not describe, the "xev" utility.  Use it to figure
out *precisely* what X thinks the keys are.  Do this before applying
the new map (so, if you've already done so, you'll need to restart X).  
I doubt you need to do anything to your XF86Config file(s), necessarily,
you just need to find the keycodes, keysyms, etc. for your keyboard.

FYI, I use this trick in every linux environment I get my hands on, and
it's always worked as is.
