[plt-scheme] enhancing the drscheme editor & GUIBuilder

You must be familiar with class.ss to understand this.
I assume the command (make-object menu-item% "Insert GUI"
(get-special-menu)...) is from within an function in
drscheme:unit:frame, which is probably some class or other type.
What you need to do is indeed (send a-drscheme:unit:frame
get-special-menu). But this is an example of the usage of
get-special-menu. It requires that a-drscheme:unit:frame be replaced
with an actual instance of drscheme:unit:frame.
To get that instance of drscheme:unit:frame, there is most probably
some function ou need to call, but I don't know that far in it. I'm
sure someone else will be happy to fill in that detail.

Good luck,
