    In order to use the Mac OS X command key for dwm commands,
    change the X11 keyboard modifier map using xmodmap (1).

    e.g. by running the following command from $HOME/.xinitrc
    xmodmap -e 'remove Mod2 = Meta_L' -e 'add Mod1 = Meta_L'&

    See also https://gist.github.com/311377 for a handful of tips and tricks
    for running dwm on Mac OS X.
