[Tfug] Keyboard navigation.

[TR]

I have two monitors driven from one card with Xinerama set to 0, off, in the
xorg.conf.  This is working well with one annoyance.   I can move between
the workspaces on one screen or the other with the key board but cannot,
with the keyboard, switch screens.     Is there a way that I can create a
keyboard short cut to move from screen to the other,

Hope this is clear and thank for any help
