Learning vi....

Okay................I think I am starting to get vi. So, when you start, to put in new text, you press a and then start typing. To switch between the command and typing modes, you press . But then, to delete a line, you type dd, and if you type in 10dd, well, then 10 lines are deleted. To delete the character the cursor is on you press x........then to quit, in the command mode :q is typed. To save :w is typed. Hmmmmm................I am starting to get this. However, for now I am sticking to pico or nano for general purpose stuff.
