How do I switch users/lock the computer?

Question

So I have a IBM Thinkpad T43P and I would like some help with it. This laptop does NOT have a window's key and I would like to be able to either lock the computer so other people can't access it or switch user. I would like to be able to do this without hibernating/logging out/shutting down. Thank you guys a bunch.

Read here. It should have a built in finger print reader.
