Thanks Peter,

A different use of markers for the beginning and end of line are backslash A and backslash Z \A\Z.
I also like to use perl one liners inside a VI session like this : % ! perl -pe 's/foo/bar/'
The : inside VI puts the editor into command line mode, the % says for every line in the file, the ! says run the following in the shell. The perl program runs on every line making the edit.
