Issue 120: Determine numlockMask automatically http://code.google.com/p/xmonad/issues/detail?id=120 Comment #5 by allbery.b: But does it use a modifier? Mine doesn't seem to, it's implemented at a different level than that. Start X11.app and run "xmodmap -pm" in the initial xterm --- I think you'll find there is no NumLock mapping (and that mod2 is Cmd aka Meta, unless you've changed settings). BTW, the fact that NumLock isn't given its own modifier slot like control, shift, and lock is indicative of how common a dedicated numlock was when X11 was developed. -- You received this message because you are listed in the owner or CC fields of this issue, or because you starred this issue.
