Revit 2009 - Productive Tool

I came across this tool earlier today when working in Revit MEP. This has been around since the launch of 2009 but I never seen it before today, as I am not much of a right-click menu type user.

You can now access temporary snap overrides from the right-click context menu when you place an element or component in the drawing area, or while moving, copying, rotating, or arraying existing elements.
