Correcting Mistakes
You can correct errors in several ways. Most editing commands require
that you select drawing objects either before or after the editing
process. However, the Undo, Redo, and Oops commands rely only on
the previous actions that you have taken. The following table
describes the most frequently used methods of correcting mistakes.
Frequently used editing commands
