Did you know that the Mac has a Terminal application for entering commands at the keyboard? Why would you want to do that? What's wrong with the graphical interface?

John Carter has some answers for us. "Well, for one, when you use the terminal both hands are constantly in the same position - over the keyboard - instead of one hand moving back and forth from the keyboard to the mouse. But if you're not a good typist that probably doesn't matter much to you anyway.

"Secondly, and this is probably the most important reason to use keyboard commands, the graphical interface actually hides a lot of functionality and detail from the user. Using keyboard commands gives you so much more control over what you want to see and do.

"Now here's an interesting tutorial that just might help anyone new to Linux to get used to keyboarding (as we call it).

"By the way, this tutorial will take you from 'why use a keyboard' to almost forgetting all about what a mouse is used for." http://osxfaq.com/tutorials/LearningCenter/
