with a code size less than 10000 byte. There is a status & input line,
where you can enter filenames, blocknames, find-texts and line numbers.
The editor commands are similary the families of \fIWordstar\fP-like 
or \fIEmacs\fP or \fIPico\fP or \fIvi\fP or \fINedit\fP editors.  
For online help press ESC:h in vi mode, else Alt-H.

.SH UNDO OPERATION DETAILS
.PP
\fIe3\fP has an UNDO mode starting in v2.2. There is no predefined
UNDO level count. You can expect to UNDO at least \fIone\fP last insert-,
delete-, overwrite- or sed_pipe-operation, but in most cases there 
are \fIlots\fP of UNDO stages available. e3 has a fixed size undo buffer 
and will use an external helper file if some deleted data is bigger 
sized than the undo buffer.  This buffer is organized as a ring, 
overwriting older UNDO information if neccessary. So one never can 
say exactly how many UNDO operations are possible. 
For using the UNDO press one of:
.TP
\fB^U
in Wordstar mode
.TP
\fB^QU
in Pico mode
.TP
\fB^_
in Emacs mode
.TP
\fBu
in vi command mode
.TP
\fB^U
in Nedit mode

.SH BUILT IN CALCULATOR
.PP
\fIe3\fP has an arithmetic calculator built in for some simple 
arithmetic calculations inside your text. Place cursor at 
begin of the task i.e. something like:  -3.002*-(2--3)=   
and press one of:
.TP
\fB^KN
in Wordstar mode
.TP
\fB^QC
in Pico mode
.TP
\fB^X^N
in Emacs mode
.TP
\fB#
in vi command mode
.TP
\fB^K
in Nedit mode
.PP
This will insert the result into text.
Use the values between -999999999999.999999 ... 999999999999.999999 
with up to 6 decimal digits and the operators +-*/  and parenthesis ( ).
Also available are p for constant PI and r for accessing the result
of last calculation


.SH RUNTIME MODE SWITCHING
.PP
You can switch to other editor mode by pressing one of:
.TP
\fB^KM
in Wordstar mode
.TP
\fB^QM
in Pico mode
.TP
\fBaltX
in Emacs mode
.TP
\fB<ESC>;
in vi command mode
.TP
\fB^E
in Nedit mode
.PP
e3 will set a prompt \fISET MODE\fP . Now enter one of e3ws, e3em, e3pi, e3vi, e3ne 
for setting \fIWordstar\fP-like or \fIEmacs\fP or \fIPico\fP or \fIvi\fP or \fINedit\fP style.



.SH OPTIONS
.PP
