Which key provides the UNDO/REDO feature in the EDIT menu?

• A. The ASSIST key
• B. The SHIFT key
• C. The ENTER key
• D. The MODIFY key

Answer: (A)

Undo/Redo in editing tasks is accessed through a dedicated editing shortcut on the control pendant. When you’re in the Edit menu and you want to revert or reapply changes, you use the key that triggers extended editing options. This key brings up or activates the editing commands including Undo and Redo, making it the primary way to manage changes during editing.

The ASSIST key is designed to unlock those enhanced editing functions, so it’s the best fit for accessing Undo/Redo. The other keys have different roles during editing: SHIFT typically modifies input, ENTER confirms actions, and MODIFY switches into a modification mode, none of which directly invoke Undo/Redo from the Edit menu.
