• On the Home tab, in the Drawing group, click Arrange:
  

  From the Arrange dropdown list, click Selection Pane...:

  
• On the Shape Format tab, Picture Format tab, the SmartArt Format tab, or the Chart Format tab, in the Arrange group, click the Selection Pane button:
  

   2.   On the Selection pane, lock any object by clicking the Unlocked icon on the right:

When you try to select a locked object to resize or modify it, you will notice:

• Unusual borders without handles for moving or changing an object. For example, a prominent border for the locked shape and picture:
    and  
• Some commands for modifying the object on the ribbon tabs are grayed:
  
• Commands for resizing and moving are grayed on the Format *** pane:
  

Note: You cannot resize and move a locked object, but you can still apply custom formatting to them. For example, it is still possible to:

• Change and format text inside the locked object,
• Change a style of locked shape, picture, or text box,
• Apply effects to the locked objects,
• Etc.
