insert vertical line - keyboard issue

[Robert]

Helo,
I' using Lyx 1.3.4 running unter Suse Linux 9.1 in Parallels on a mac. I want to
insert the vertical line which is on my (german) keyboard on the ><-key left
from y. Normally I use AltGr+> but this key seems to be mapped wrong, since the
< and the > don't work. Is there any way of inserting a key in Lyx, like with
the alt+Number way of entering keys.
thanks
Robert
