Edit > Undo
Reverses up to the last 10 view manipulations that you completed. You can also use the Undo command during navigation. As you stop at various locations during navigation, you can use the Undo command to return to a previous location. This can be done when you are using navigation commands. After you select the tenth undo operation in a work session, the Undo command is disabled until you move again and the undo operation count restarts.
You can also access the Undo command by pressing Ctrl + Z on your keyboard.
