We need evidence for that, and we need evidence that would explain why
xterm.el does have a translation for that key.

AFAIU, Thomas just says that he doesn't know of any standard xterm
assignment to the Menu key.  I already knew that, because I looked
into the xterm sequences documentation when you first reported the
issue.  So what Thomas wrote doesn't tell me anything new.

I don't think using S-F6 for this is a good idea.  F10 is our key for
menus, so S-F10 sounds a lot better.

I don't understand why would we need to request anything.  If this is
for the Print key, then since it seems that no keyboard has it, we are
good.
