Although this has always historically been true (still remember the X11
lock-screen security fiasco), is it still true today?
Things like Firefox seem to be able to do the "right thing" --
desktop-wide shortcuts are triggered even if a menu is open (although to
say it all the menu closes, and then the shortcut triggers, so it won't
help OP anyway for their specific use case...).
