Issue 120: Determine numlockMask automatically http://code.google.com/p/xmonad/issues/detail?id=120 Comment #4 by YitzGale:

Keep in mind that NumLock is a PC-ism; Macs don't have it (and mod2 defaults to being the Cmd key in X11.app)

My MacBook has a NumLock key. I don't know if it's mod2 though. I don't run xmonad on the Mac. -- You received this message because you are listed in the owner or CC fields of this issue, or because you starred this issue.
