First Three Charactors

Auto-complete is when you type in a few charactors and then a list of previous entries appear that begin with those charactors. If you only type one letter then a lot of matches appear. I first saw this on a DEC MicroVax, it was built into the command line of the Operating System. It is a good idea. I wish a lot of the boring things in life could be set to autocomplete. Does that wish show I am lazy or would it be more efficient?
