This is a really good introduction to vim. It is better to think of it as a grammar to manipulate text. A few additional things that have saved me keystrokes.

This is a really good introduction to vim. It is better to think of it as a grammar to manipulate text. A few additional things that have saved me keystrokes... replace mode (R) insert normal mode (<c-o>) paste from a register in insert mode (<c-r>reg) expression register (=) clipboard and active selection registers (+, * respectively) command ranges (e.g. 10,+5s/foo/bar/g) miscellaneous commands (:global, :argdo, :normal, etc...)
