[Xmonad] "Empty" KeyMask: 0 vs AnyModifier vs ...?

[Andy Gimblett]

Hi all,

I'm trying to set up keybindings in Config.hs which require no
modifier at all.  eg, to launch a terminal when I hit F2.

The following works:

    , ((0,                  xK_F2    ), spawn "urxvt")

but doesn't feel "right".  Is there a better candidate for the KeyMask
field?  I thought anyModifier might be right (something Anselm once
said seemed to support that:

no, it doesn't.

Any thoughts?

Thanks,

-Andy
