It ought to work, shouldn't it? As I said, hibernate/wake really is hard coded into the <ctrl>+F3 combination. In custom shortcuts, you can't grab that one. I'm going to see how many others I am allowed to use. <ctrl>+ a,b,c,etc, or alt or something. I really don't want a three key combination when you have to be really slick. > > It's beginning to feel more and more like the product I used to use - what was it now?

I did find that there are lots of different ways to create keyboard shortcuts, so if it is something that's been set in Ubuntu it could be tricky to pinpoint. However, the fact that this combination wakes the machine up from sleep leads me to ask whether the F3 key is the hardware sleep/wake key - does F3 have the usual sleep/wake symbol (typically a crescent moon) on it? Does pressing F3 on its own also put the machines to sleep? Grant. :)
