The View back feature allows you to return to the previous sixteen view entries. Note that if you back up four views and then change the view, those four are lost from the chain. There are two different types of view function, "major" and "minor." A "major" modification is anything that requires additional user input or an autoscale. A "minor" modification would be any of the keyed or incremental modification options. The current view is saved in the back up chain before and after each major modification (if the view had changed).

For example, if you were to use the keyed Pan functions ten times, then Autoscale, it would result in two new views being added to the view history. Each viewport has its own history list, so changes made to one viewport cannot be undone through another.
