How do I collapse all entities to just headers when editing an Entity Framework EDMX model in Visual Studio 2010?

Each block representing an entity has an icon to collapse it to its header (hiding all properties from the diagram) in the header's right-top corner. How do I collapse them all without click开发者_运维问答ing each one manually?

You will have to assign a key to the command as it does not have one and I cannot find any context menu that contains it...

Tools>Options>Keyboard>Show Commands Containing: OtherContextMenus.MicrosoftDataEntityDesignContext.Diagram.CollapseAll
