You mean it works on your system. There's no guarantee that it will
work on anyone else's. The mapping between keys and keysyms and the
mapping between keysyms and modifier bits are both dependent upon
configuration. E.g. on my system:

	mod1        Alt_L (0x73)
	mod2        Num_Lock (0x4d)
	mod3      
	mod4        Meta_L (0x40)
	mod5        Mode_switch (0x71)

[Alt_L is the left-hand Windows key, Meta_L is the left-hand Alt key.]
