HP48G soft menu toggle: How?

[BruceH]

It's possible to create 'toggled' menu items using nothing more than userRPL.

Page 189 of Bill Wickes' "HP48 Insights", vol. 1. has an example of how to use a graphic for the menu item - so all you need to do is create 2 grobs of the right size, one with the toggle 'on' and the other 'off' and have the key action swap the menu over to the alternate display before doing whatever it is that needs to be done.
