As others posted above, open a terminal and type vimtutor
to get to the built-in Vim tutorial. Grab your drink of choice and before the cup is empty you will be a solid basic Vim user and well on your way to becoming a power user!
Long ago I wrote my own simple "Quick start" guide for Vim that will get you past the "what the heck is happening?!" point very quickly, find it here
. You might find it a good place to start as well.
Pay no attention to the "Vim is too hard!" FUD! Vim is among the most useful and easiest to learn tools you have on your computer! Learn it and use it! You will be glad you did!
