you probably don't have vim, as this is an extension of Vi (although essentially it is the same thing). try this to get vim (if you're using debian os):

sudo apt-get install vim

I have a great cheat sheet for vi , but it will take practice to learn how to use it effectively.

Here are some of my most used commands for vi/vim:

i - enter input mode
esc - escape input mode
del - delete text
:q - quit
:wq - write and quit
:q! - quit without saving
dd - deletes a whole line
shift+a - goes to the end of a line and enter input mode

As for the ex command, I'm not sure what that does without being able to test it.

Thank you...But after I have used vi for sometime, I still find it not as convenient as most graphical editors, isn't it? Especially there is no drag to us in vi.

Yes you're correct. A lot of old school programmers love vi, and that's all I use in work. It's because we use Subversion for version control, and it's good to keep everyone using the same editor for consistencies in the team.

If I was working alone, then I'd most likely use a graphical editor like gedit.
