After an hour or two of manpage and Google searching and finding no solution or good resources, I've come for help!
I have set my Caps Lock key to Ctrl using
setxkbmap -option ctrl:nocaps - this works perfectly fine.
However, since I use [awesome], and an IBM model M which lacks the meta key, I need my left alt key to replace the windows key. Using
xkeycaps I was able to get this to work, except it killed my arrow keys and End. Problematic.
Unfortunately, documentation on setxkbmap options are sparse. and I can't find the proper option to use.
Thanks for any links/solutions.
