the installation floppy (and in any references in new user docs for editing files) since tossing a novice into vi with no help or clue as to what the key bindings are is both cruel and in violation of the Hague Convention. It's also much SMALLER than vi and even supports emacs key bindings for those so inclined. Submitted by: "Hugh F. Mahon" <hugh@nsmdserv.cnd.hp.com>

.SH DESCRIPTION
|
|
The command
|
|
.I ee
|
|
is a simple screen oriented text editor. It is always in text insertion
|
|
mode unless there is a prompt at the bottom of the terminal, or a
|
|
menu present (in a box in the middle of the terminal). The command
|
|
.I ree
|
|
is the same as
|
|
.I ee,
|
|
but restricted to editing the named
|
|
file (no file operations, or shell escapes are allowed).
|
|
.PP
|
|
For
|
|
.I ee
|
|
to work properly, the environment variable
|
|
.SM TERM
|
|
must be set to indicate the type of terminal being used. For
|
|
example, for an
|
|
.SM HP 700/92
|
|
terminal, the
|
|
.SM TERM
|
|
variable should be set to "70092". See your System Administrator if
|
|
you need more information.

A paragraph may be formatted two ways: explicitly by choosing the

\fBformat paragraph\fR menu item, or by setting \fIee\fR to automatically

format paragraphs. The automatic mode may be set via a menu, or via the

|
|
There are three states for text operation in \fIee\fR: free-form, margins,
|
|
and automatic formatting.
|
|
.PP
|
|
"Free-form" is best used for things like programming. There are no
|
|
restrictions on the length of lines, and no formatting takes place.
|
|
.PP
|
|
"Margins" allows the user to type in text without having to worry about going
|
|
beyond the right margin (the right margin may be set in the \fBsettings\fR
|
|
menu, the default is for the margin to be the right edge of the
|
|
terminal). This is the mode that allows the \fBformat paragraph\fR menu
|
|
item to work.
|
|
.PP
|
|
"Automatic formatting" provides word-processor-like behavior. The user
|
|
may type in text, while \fIee\fR will make sure the entire paragraph fits
|
|
within the width of the terminal every time the user inserts a space after
|
|
typing or deleting text. Margin observation must also be enabled in order for
|
|
automatic formatting to occur.
