You can use Undo and Redo for changes to the Intergraph FreeView display and navigation operations.
Undo (CTRL + Z)
Reverses up to the last 10 view manipulations that you completed. For navigation, as you stop at various locations during navigation, you can use Undo to return to a previous location. After you select the tenth undo operation in a work session, the Undo command is disabled until you move again and the undo count restarts.
Redo (CTRL + Y)
Re-applies the previously undone view manipulation.
