If you don't know how to use vi (or xvi) at all, you should not
read through this help text; it is intended simply as a reminder
for those who already know how to use the editor.
To get out of xvi, type the following:
:q!
and then press RETURN.
The rest of this file contains a summary of xvi commands.
If you remember the commands ^D (control-D) and ^U (control-U)
then that will be enough to get you around this help file.

their action. For instance, to go to line 37 of a file, you can
type
