Hello Larry,
I don't think item 16 addresses my issue. The original FW did not have a keypad icon at all. You just had to know to click in the white area to the right, hence my calling it an Easter egg. Attached is a photo of a recent unit from nooelec showing the numeric entry bar with no keypad icon.. FW in new units is the same as the older devices. I would address this with a photo that highlights the magic area like the second photo. Text like : "Note that earlier level firmware defaults to a one line numeric entry bar as shown here. Click in the white area to the right of the numbers (red circle here) to bring up the full keyboard." or some such verbiage.
Another thing I noticed is that the menu map on the last page while very useful is down right hostile to a printer because of the dark background. I took a quick hack at it with GIMP to make it more printer friendly. I'll attach what I got but it might need more work if you want something like this. Better still would be to get the originator to change the colors.
Thanks for the interest, Joe
