You can backtrack your
recent actions using one of several methods.
Undo a Single Action
simplest method of backtracking is to use Undo on the Standard toolbar or
the U command to undo
a single action. Many commands include their own U (undo) option
so that you can correct mistakes without leaving the command. When
you are creating lines and polylines, for example, enter u to
undo the last segment.
By default, the UNDO
command is set
to combine consecutive pan and zoom commands into a single operation
when you undo or redo. However, pan and zoom commands that are started
from the menu are not combined, and always remain separate actions.
Undo Several Actions at
Use the Mark option of UNDO to mark an action
as you work. You can then use the Back option of UNDO to undo all
actions that occurred after the marked action. Use the Begin and
End options of UNDO to define a set of actions to be treated as
You can also undo several actions at once with
the Undo list on the Standard toolbar.
Reverse the Effect of Undo
You can reverse the effect of a single U or
UNDO command by using REDO immediately
after using U or UNDO.
You can also redo several actions at once with
the Redo list on the Standard toolbar.
You can erase any object that you draw. If you
accidentally erase the wrong object, you can use the UNDO command
or the OOPS command to restore it.
For more information, see Erase Objects.
Cancel a Command
can cancel a command without completing it by pressing Esc.
