Need help locating menu functionality

[tmitchel@BBN.COM]

  I seem to recall seeing a function that will allow a user to order a list
of choices in a menu by dragging choices up or down in the list.
Unfortunately I spent quite some time with apropos and the Document
Examiner yesterday and couldn't locate it.  I think it was actually
an addition to Genera that was part of the color system (written by SGD).
I have looked through my old Color System addendums and release notes as
well to no avail.  Can anyone give me a pointer to this functionality?

Thanks,
