Delete Rows
This option is also available on the Lookup Table Editor tab for Lookup Tables.
On the application title bar, or the Quick Access Toolbar, click Undo (CTRL + Z) to undo the last edit. The Undo function records the edits you have made and will undo those edits in reverse order. Following an Undo, click Redo button (CTRL + Y) to re-apply the last edit.
