Since XForms is not an X Toolkit based library, setting app defaults
translations won't do much for you.
Unfortunately, as far as I can tell, XForms is only really aware of
Button[123] -- for example, in the definition of button_down:
#define button_down(mask) (((mask) & Button1Mask) || \
((mask) & Button2Mask) || \
((mask) & Button3Mask))
The best thing I can suggest is to create pre or post handler and deal
with the raw XEvent yourself.
