Undoing Mistakes You
Have Made
What if you decide you don’t like a change you just made? How can you
put the text back the way it was without having to retype everything? Look
on your template and find the key that is labeled UNDO. Press it. TEDIT
reverses the last change you made to the text; in this case, the lines in the
paragraph return to their uneven state.
Press UNDO again and watch what happens. The sentence you deleted in
the previous example reappears. Each time you press UNDO, the previous
change you made to the text is undone. If you want, you can undo all the
changes you made since you opened the file for this editing session. With
UNDO you don’t have to worry about making mistakes; if you make a
mistake, you can just UNDO it.
What if you UNDO something and then decide that you really wanted the
way you did it after all? Press REDO and it goes back to the way it was
before you pressed UNDO. Try it. Press REDO until you see this message
appear:
1) There are no changes to UNDO or REDO C00.
TEDIT displays this same message if you pressed UNDO until you had
undone all the changes you made since you started the editing session.
Note You can undo or redo only the changes you make during a single editing session. If you exit
from the file, TEDIT does not remember the changes you made and thus is not able to undo
them.
