To undo and to do againTo undo and to do again
As usual, the operation Undo (Edit menu, Alt U) is there to recover after making a
mistake. It will undo the last operation performed, or in case of
ordinary typing on one line, whatever has changed on that line since
you started typing there.
Selecting Undo twice is equivalent to doing nothing. Edith does not
know a redo command as found in many other text editing software.
To recover from a more complex mistake, use the trash buffer.
Undo is often only available in the window you last worked in. This
is because all text windows share a bit of memory (a buffer) that stores the information needed for recovery.
USING THE TRASH BUFFER
For the sake of simplicity, Edith has the concept `undo plus undo is
equivalent to doing nothing'. This has the disadvantage that as soon
as you make two subsequent mistakes, there is no easy way to recover the
old text. However, in most of the cases, this data will be
available under Trash buffer (Windows menu, Shift Ctrl T). The trash buffer contains all material that
the Undo (Edit menu, Alt U) function has had to remove earlier. The old text can be
selected, and dragged-and-dropped back to the original window easily.
In many cases, the trash buffer system turns out to be more versatile
than a so-called multi-stage undo system. The most common example
is: you type some good text (A), remove it by accident, then type a lot
of good text (B). To get text A back in a multi-stage undo system, all
of B would be lost.
THE DRIBBLE RECORDER
When you are typing, your actions are continuously being recorded.
Recording starts when you type or delete a character, and then records
subsequent typing, cursor motion and deletion on the same line.
Recording stops automatically when (1) you move to a different line, (2)
choose some non-line based operation or (3) walk left-then-right, or
right-then-left. When recording stops automatically, cursor motion at
the end of the recorded sequence is discarded. Recording can be
switched on/off manually with the Rec button in the
status/input line; this may be necessary if you
wish a recording to begin or end in cursor motion operations.
The recording can be played back using Repeat dribble (Edit menu, Ctrl R). Three recordings can
be saved under keyboard combinations Alt 1, 2, 3
using Store dribble (Edit menu, Ctrl T).
It is possible to play back a dribble over several lines
simultaneously; just select the lines and Repeat dribble (Edit menu, Ctrl R).
