Using @IsDocBeingEdited in Form formula

I didn't know (or I forgot) this was possible, but a view is aware of if a document on the web is being opened for reading/editing, so you can use one form for editing a document, and another one for opening the document.

Example:

@If( Form="Category" & !@IsDocBeingEdited ; "Overview" ; Form )

This is useful for me due to a bad application design choice in one of the application templates I manage.
