CommandParameter document needed

This is actually more of a Silverlight Viewer enhancement request...

The combo box for adding new menu items to the "I Want To Menu" provides a list of available entries for the "Command" field, but nothing for the "Command Parameter" field.  An html-based help system as found in the ADF manager would be very helpful. 

The same would apply to the "Add Tool" combo box for adding a tool to the toolbar.  Available entries for the "Command" field are there, but nothing for the "Command Parameter" field.

Thanks,

Steve
