changing windows without clicking

[Karl Goetz]

hi all
I got a dual head setup running more-or-less over teh weekend, along
with x2x.
What I'm after is that instead of needing to click or alt-tab to change
windows, i can move the mouse over onto the new window and it activates.
I thought gnome had an option to do this, am i correct in that?
I'm happy to hack with gconf, i just want to know the options there
before i start !
