OK - this is trivial if you have an understanding of whats going on
All this in HandleButtonClick event
add a constannt at the top
Const conCmdOpenQuery = 9
in the case statement, add the following at a suitable point
Case conCmdOpenQuery
DoCmd.OpenQuery rst![Argument]
now, in your switchboard items table, just add options, with command value 9.
-------------
now I suspect the reason MS didint put it there, is because its unusual to want ot open a query directly. If its editable, you lose control of data entry, and it becomes dangerous. But its easy to do, as explained
