The Vim page up and page down keystrokes

Vim FAQ: What are the Vim page up and page down keystrokes?

Short answer:

The Vim page up keystroke is [Control][b]. You can remember the 'b' by thinking "back".

The Vim page down keystroke is [Control][f]. You can remember the 'f' by thinking "forward".

I use those two Vim keystrokes most of the time, but you can use other keystrokes in Vim to move up and down, as shown here:

[Control][b] - Move back one full screen
[Control][f] - Move forward one full screen
[Control][d] - Move forward 1/2 screen
[Control][u] - Move back (up) 1/2 screen

I hope these Vim page up and page down commands are helpful.
