Mill Tip: Undo/Redo or Just Say No!
Have you ever made a mistake while editing a record and didn’t know how to fix it? Following are two easy shortcuts that will help. To UNDO your last action (you can cancel up to ten of your last editing actions):
Hold down the “CTRL” button and the “z” key
OR
Under “Edit” choose “Undo”
And to really confuse you - you can always REDO your most recent UNDO (you can cancel up to ten of your last “undo” actions):
Hold down the “CTRL” button and the “y” key.
OR
Under “Edit” choose “Redo”
But never fear - if all else fails just say “NO” when you close the record and the system asks if you want to save your changes!
