Undo and Redo Commands
Use the Undo command to step back through every action you made, including pan and zoom. Use
the Redo command to step forward through those actions again. These commands are conveniently
located on the Quick Access toolbar. You can Undo at any point in the drawing session, even within
some of the draw and modify commands. However you can only Redo immediately after an Undo
Command.
You may also type the Undo command at the Command line. Enter U and press ENTER. If you continue
to press ENTER, the Undo command will be repeated. If you enter the entire word UNDO at the
Command line and press ENTER, you will see a list of Undo options at the Command line prompt.
If you are working in the AutoCAD Classic workspace the Undo and Redo buttons include down arrows
that reveal lists which you can choose to undo or redo up to a selected item or step.
