Is is possible to call up the Start Menu with a DX object? 

OD+ has a built-in docklet that will call up the Vista start menu, but a DX object does not seem to have the option to change its type to something with that functionality.  I can change the object from 'layer' to 'shortcut' but have been unable to find a way to make a 'shortcut' send a keystroke (i.e. the 'Windows' key) that would call up the Start Menu, like pressing the Windows key would. 

Is there a way to use a script to send a keystroke to the system?

Thanks.
