Is there any software that enables you to "look" into a friends computer and take over his mouse and control of computer to solve a problem or situation that might arise?

I'm teaching a friend some computer basics and when we're chatting on Yahoo messenger, it's sometimes hard to explain correctly what I'm talking about, and if this program exists then I could simply ask his permission, log into his computer, show him right in front of him what i did, and then exit back out with the saved changes.
