LabVIEW 2009-Tips to create automatic controls & indicators for functions

In LabVIEW 2009, i came to know one interesting feature to create terminal controls & indicators for function. That is as follows,
For example,
1. Keep & select any one function in block diagram(eg: Add function)















2.Select that function.(Now it will be highlight)
3.Use key strokes Ctrl + Space.
4.Next use another key stroke Ctrl+ D (Use Ctrl+Shift+D to create constants).
5.Now you can see the magic .The terminal controls & indicators of that function should be created automatically.














This feature available only in LabVIEW 2009. I tried with some premitive functions & standard VI's its works fine.
