Just when you thought you already knew it all.
I've been using the text editor VI for a long time, like over 20 years. After 20 years, there's not a lot that surprises me about vi anymore. Sure vim and gvim have fancy new features, but they're not real vi so I don't worry about it much.
Pierce pointed me at this, and as I was reading the reference contents I noticed something new:
:> n - indents n lines.
Not a earth shattering command, but its always fun to find out something new about something you've been using for over 20 years.
