URC 8910 (and possibly 9910) reallocating memory.

Xshift-fav is on the Special Functions tab for each device

Ah, I forgot to check there!

Just FYI, here's a tip when dealing with older remotes like this, if you fire up KM, select the URC-8910 and then go to the Layout tab, it will show you which buttons are available in each device mode, and you'll notice that the list is longer for CABLE than VCR, so it's a better mode for upgrades.

Squeezed out another 30 bytes all told, so added one last thing on the F.Rew button to Skip back 10 seconds on a double press. I now have 25 bytes. Thanks for your help, though I would still like to know how to move the boundary so that I can have a bit more Move/Macro space and not so much Upgrade space.
