Click the binoculars to open a drop down list of all the symbols on the diagram. Scroll down the list, or enter the first letter of the name of the object in the text box at the top of the list. As soon as you enter a letter, the first entry in the list with that letter goes to the top of the list. If there are no objects with that letter, the list goes back to the beginning.

Click the object you are interested in. Click the Find button. The focus of the diagram immediately shifts to the chosen symbol. The chosen view size of the diagram does not change.
