Sorry to hijack your thread Jaime_S, but I wanted to thank Jo for this link.

I've had my laptop for nearly a year now, and that's the first time I had heard of that key. I saw it there but wasn't game to press it, but I just looked it up and read what it's for. I think I may need to look at some more keys & bits so I get proper use out of them all. I'm a slow learner when it comes to computers as I'm always afraid of mucking things up!

I found and used my webcam for the first time a few days ago too, so I know that works.
