Summary: how?

I noticed that the new LSC has a pop up menu when you option-click in the
title bar of a window;  Also the choose file dialog in the hfs has a pop
up window to change directories.  

I was thinking how nice it would be to be able to do this in general.  
It seems that the thing to do would be to make use of the MDEFs that
already are around.  According to the specification for custom MDEFs
these take as an argument the rectangle to draw the menu in, so it
seems quite plausible.  

I tried to do it but was unsuccessfull.  How could one call an MDEF
by oneself?  More generally, how does one call a code resource?  
None of this is documented in Inside Mac, volumes 1-3.  
Please mail to me.  I will summarize for the net.
