Setup code 11463 is related to 10463. The codes work the same for digits, vol+/-, Ch+/-, etc. But 11463 has a larger number of keys defined (including some inputs), and sends different function codes for the arrow keys.
You can see which Extended Function Codes are different by using the tool mdavej cited.
Maybe 11463 is better. If you can find keys which do what you want, but it takes both setup codes to do everything, we can show you how to keymove EFCs from one setup code onto the other, effectively combining the best of the two setup codes.
