.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
|
|
An editor with similar user-friendly qualities but more features is available
|
|
and is called
|
|
.I aee.
|
|
.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.

.SS "Control keys"
|
|
To do anything other than insert text, the user must use the control keys (the
|
|
.B Control
|
|
key, represented by a "^", pressed in conjunction with an
|
|
alphabetic key, e.g., ^a) and function keys available on the keyboard
|
|
(such as
|
|
.BR "Next Page" ", " "Prev Page" ,
|
|
arrow keys, etc.).
|
|
.PP
|
|
Since not all terminals have function keys,
|
|
.I ee
|
|
has the basic cursor movement functions assigned to control keys as well as more
|
|
intuitive keys on the keyboard when available.
|
|
For instance, to move the cursor up, the user can use the up arrow key, or
|
|
.BR ^u .

Since many shells provide an Emacs mode (for cursor movement and other editing

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.

"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.

.IP "\fBtab expansion\fR"

Tabs may be inserted as a single tab character, or replaced with spaces.

The search operation can be sensitive to whether characters are upper- or

Lines can either be truncated at the right margin, or extend on forever.
|

While typing in text, the editor can try to keep it looking reasonably well
|
|
within the width of the screen.
|
|
.IP "\fBeightbit characters\fR"
|
|
Toggles whether eight bit characters are displayed as their value in angle
|
|
brackets (e.g. "<220>") or as a character.
|

.IP "\fBinfo window\fR"
|
|
A window showing the keyboard operations that can be performed can be

displayed or not.

two 8-bit quantities. This works primarily with the Chinese Big 5 code set.

Additionally, the user may direct the contents of the edit buffer out to

a shell operation (via a pipe) by using the left angle bracket

(">"), followed by a "!" and the shell command to execute.
|
|
The output of a shell operation can also be directed into the

These can even be used together to send output to a shell operation and
|
|
read back the results into the editor.

So, if the editor contained a list of words to be sorted, they could be

sorted by typing the following at the command prompt:

This would send the contents of the editor to be piped into the

The old information would have to be deleted by the user.

.SS "International Code Set Support"
|
|
.I ee
|
|
supports single-byte character code sets (eight-bit clean), or the
|
|
Chinese Big-5 code set.
|
|
(Other multi-byte code sets may function, but the reason Big-5 works is
|
|
that a two-byte character also takes up two columns on the screen.)

.SH WARNINGS
|
|
The automatic paragraph formatting operation may be too slow for
|
|
slower systems.
