I've seen people type just the start of commands and then press something and get the full command or a directory! What are they pressing, this is an incredibly useful part of linux in my opinion and theres not a lot of info on how they do it, I'm sick of typing whole commands when just a few letters and whatever magic button there pressing fills in the rest.

I'll give a quick example of this in case people dont understand...

the people i've seen do this have typed for example: cd /real (then whichever magic button their using) and got to cd /reallylongdirectorylocationhere.

Any ideas?

It's called "Tab completion" Does that give you a clue to what key they're pressing.

tabcompletion?! No idea what that means at all, just kiddin hey this is a newbie forum you know, don't need to get angry quite so quickly!

Never the less thanks for telling me, this should be the first thing in all linux books in my opinion!
