Right now, I am Learning Python the Hard Way,  after lesson 10, I decided screw gedit
I am going to learn vi. Vi is known to have a steep learning curve, but  these basic commands are enough to help you to get through Learning Python the Hard Way.

The good thing about this course is you start with rather small code, not much then 10 lines in the first couple of lessons.  This makes it perfect to get a more then decent grip on vi,  knowledge of the basic workings of the Terminal is assumed though!

If you want to see some vids about vi first,  then I would suggest watching the Lullabot vids called Command Line Basics, at vid 9 she discusses vi. The whole series is worth watching though

This cheat sheet is based on this vi command summary, I added one help full Python command
