Protect

Specifies the characteristics of a selected shape that you want to lock (lock: A setting that limits the ways that users can change a shape. For example, a lock on a selection handle prevents the user from resizing a shape using the selection handle.).

1. Width
   Locks the selected shape's width to prevent resizing. To lock a 1-D shape against rotation, you must lock its width.
2. Height
   Locks the selected shape's height to prevent resizing.

Aspect ratio

( Ctrl + Shift + E )

Locks the ratio between a shape's height and width so that its proportions won't change when you resize it.

1. X position
   Locks the x (horizontal) position of a shape so that it cannot be moved.
2. Y position
   Locks the y (vertical) position of a shape so that it cannot be moved.
3. Rotation
   Locks a shape so that you cannot rotate it by using the Rotation tool. You can still rotate a 1-D shape by dragging its endpoints. To lock a 1-D shape against rotation, you must lock its width.
4. Begin point
   Locks the begin point of a 1-D shape to a specific location so that it cannot be moved.
5. End point
   Locks the end point of a 1-D shape to a specific location so that it cannot be moved.
6. Edit Text
   Locks the text in the shape so that it cannot be edited.
7. Format
   Locks the formatting (line, fill, text, shadow, corner rounding, transparency) in the shape so that it cannot be edited.

   Locks the shape so it cannot be selected. Tips: To cancel the protect from selection, right-click the shape in the page, and then click Cancel Protect from Selection.
9. From deletion
   Locks the shape so it cannot be deleted.
10. From group formatting
    Locks the formatting (color, fill, line, and shadow) in sub-shapes so that they do not change if the grouped shape is formatted. You can still format a sub-shape by selecting it.
11. From theme
    Locks the shape so that it does not change if a color theme is applied.
