Undo Several Actions at Once
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 a group.
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.

it.

layers, linetypes, and text styles. With PURGE you can also remove zero-length
