More and Vi (or) More Vi

To edit a file after looking at it with "more"

Press the letter "v" key and you will be placed
in a vi session.

Quitting the vi session will bring you back
to viewing the file with the "more" command

This will not work with piping a file to "more".

This works:

$ more /etc/hosts

This does not:

$ cat /etc/hosts | more
