Oh, well.

pinentries like to grab keyboard and mouse to prevent you from
accidentially typing your PIN or passphrase into a terminal window or
your IRC input line :)

If you don't like it, there is a --no-grab option.  pinentry doesn't
parse any config files, but the option is passed through by gpg-agent
if you put it into .gnupg/gpg-agent.conf, I think.

This would also be a work around for the menu key problem, I'd guess.

Can we disable this conflicting grab in pinentry-qt somehow?

Mmh.
