Can a "Specify Entry Number" shortcut be made in PowerPoint?

[S. Patrick Eaton]

Hello, Fellow Felixians.

One of the many good things in the more recent Felix releases was the
ability to assign custom shortcuts to various commands. I get a lot of
use out of this feature, but I've noticed that the "Specify Entry
Number" command that is available in Word doesn't seem to have a
counterpart in PowerPoint.

You can specify an entry number in PowerPoint by using Alt, X, X, Y, Y,
however, so it seems like it should be possible to assign a shortcut to
that action. Does anyone know if there is a way to do so?

With many thanks in advance for any and all responses,
