Did you know you could search for Actions and Columns in the Find Uses ‘drop down’.
Not sure if this is a feature or a bug but after you do a Find Uses further ‘Find Uses’ can be initiated directly from the “Search for usage of:” drop down which includes all tables/columns AND at the bottom of the drop-down for the table it includes the list of actions associated with that table. Unfortunately it doesn’t take you to the Action editor after selecting an action so I think this is a bug.
