Essential Vi Commands
February 18th, 2008 by Giovanni
Vi is one of the ordinal editors on Unix, and now Linux machines. It has a minimal interface but can be very fast and is great if you have a slow connection.
The Wikipedia article http://en.wikipedia.org/wiki/Ed_(text_editor)
has a very nice 10 line summary.
This note is primarily so I can remember where to find it again :-)
