How to edit a view?

A user contacted me. They want to create a view that covers the previous month.  I walked them through the search criteria, and showed them how to set the opened before and opened after fields.  That search returned to them the info they wanted.

They wanted to save the query, so I walked them through saving the view.

However, the next question was "how do I change this next month to show the a different month?"

I have been looking, but have not yet figured out how a user with the ability to save views can edit those views.

Where does that functionality reside? I don't see it in the Favorites and Dashboards. I tried the "Open View" menu option in Incidents, for example, and it runs a view - but it is not clear how to modify the parameters of the view.
