When experimenting with a file, or when reading a documentation file,
it is best not to be able to write to that file. Most people use the
F10 key (save and exit) when leaving the editor. With this habit,
quick accidents can happen without warning. The View-Only mode, which
is indicated by a `V' as the seventh status character, is included to
help prevent against such loss of data. In this mode the buffer cannot
be written to a file. If a write is attempted, an error message is
given. This mode can be selected with Alt-V. It can be
`de-selected' - in case you change your mind - with Ctrl-V. In
that case, the backup mode that is in the default buffer is selected as
the new backup mode. For more information about the default buffer, see
the chapter on stedi's default settings p. .
