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 calculations 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.
