Pick up from last line in vimrc

Question

In my.vimrc file, how can I make it so that when I tab in X amount of times about (let's say 3) that when I hit return, it'll also be tabbed in 3 times?

Answer 1

:set ai

ai is auto-indent

To disable auto-indent:

:set ai!

Answer 2

This should be enough... set smartindent
