Reverting changes to layout object, part, or background styles
You can remove all layout-level changes you have made to an object, layout part, or the layout background to return to the saved style.
Tip  You can choose Edit menu > Undo, and Edit menu > Redo to incrementally revert and reapply style changes.
To revert changes to object, layout part, or background styles:
1.
In Layout mode, select an object, a part label, or click anywhere in the layout background to select it.
See Selecting objects.
Note  To select the layout background, ensure no objects or parts are selected.
2.
Click Inspector Inspector button in the layout bar, then click Appearance.
3.
For Style, click the red arrow Unsaved style button and choose Revert Changes to Style.
The format of the object, layout part, or layout background returns to the appearance it had when you began making changes. The arrow changes to gray Saved style button.
Note  If you have not made any layout-level changes, Revert Changes to Style is dimmed in the style drop-down menu.
