Yes, I tried that and it had no effect at all.  I've just checked again
and that box is checked and I most definitely can't use the left Alt key
in the xfce4-terminal.  If I run (for example) an xterm *from* the
xfce4-terminal then the Alt key works as expected in the xterm window.
So it's not my environment causing the problem, its xfce4-terminal.
