Almost all text input on
the

operating system
is done with
the text-editor
.IT ed .
This memorandum is a tutorial guide
to help beginners get started
with text editing.

Although it does not cover everything,
it does discuss enough for most users'
day-to-day needs.
This includes
printing, appending, changing, deleting, moving and inserting entire lines of text;
reading and writing files;
context searching and line addressing;
the substitute command;
the global commands;
and the use of special characters for advanced editing.
