You can use vi to edit files via SHELL. It is very helpful when are you are managing a system remotely.

Usage

usage: vim [arguments] [file ..]       edit specified file(s)
   or: vim [arguments] -               read text from stdin

^F - move forward one screen

^B - move backward one line

^D - move forward one half screen

^U - move backward one half screen

^R - redraw screen ( does not work with VT100 type terminals )

^L - redraw screen ( does not work with Televideo terminals )

Inserting

r - replace character under cursor with next character typed
