Question : Switching to the GUI Designer from a source file

While in the Netbeans GUI designer it provides you with a a couple of buttons to switch between the Designer and the Source for that resource.  Once I click on the "source" button those buttons disappear and I cannot figure out how to get back into the GUI designer for that resources without closing the source file and the reopening it.  Does anyone have a shortcut for getting back into the designer?  

Thanks.

The 3rd and 4th entry in the table.

Previous Inner View //switching views in Editor .. e.g. Source/Design in Matisse: Ctrl + Alt + Page Up
Next Inner View // switching views in Editor .. e.g. Source/Design in Matisse: Ctrl + Alt + Page Down

I do not have any Netbeans installed here and can't check it. But maybe it helps you.
