E3 - A mini text editor
SYNOPSIS
e3[ws|em|pi|vi|ne] [filename]
DESCRIPTION
e3 is a complete mini application written fully in assembler, with a code size
less than 13000 bytes. There is a status & input line, where you can enter file-
names, blocknames, find-texts and line numbers. The editor commands are simi-
lary the families of Wordstar-like or Emacs or Pico or vi or Nedit editors.

Wordstar key bindings only.

UNDO OPERATION DETAILS
e3 has an UNDO mode starting in v2.2. There is no predefined UNDO level count.
You can expect to UNDO at least one last insert-, delete-, overwrite- or
sed_pipe-operation, but in most cases there are lots 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:
^U in Wordstar mode
^QU in Pico mode
^_ in Emacs mode
u in vi command mode
^U in Nedit mode
BUILT IN CALCULATOR
e3 has an arithmetic calculator built in for some simple arithmetic calcula-
tions inside your text. Place cursor at begin of the task i.e. something like:
-3.002*-(2--3)= and press one of:
^KN in Wordstar mode
^QC in Pico mode
^X^N in Emacs mode
# in vi command mode
^K in Nedit mode
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
RUNTIME MODE SWITCHING
You can switch to other editor mode by pressing one of:
^KM in Wordstar mode
^QM in Pico mode
altX in Emacs mode
<ESC>; in vi command mode
^E in Nedit mode
e3 will set a prompt SET MODE . Now enter one of e3ws, e3em, e3pi, e3vi, e3ne
for setting Wordstar-like or Emacs or Pico or vi or Nedit style.
OPTIONS
e3 accepts a filename for text editing. Switch the editor mode depending of the
binary name, one of e3ws, e3em, e3pi, e3vi, e3ne
