Do you mean post 4 or 6 codes?

If you mean Post 6.

I don't have the codes but if you decode each of your learnt hex codes with IRTools and by using the OBC (Function) number and then convert it to a hex number you can use those short hex codes.

E.G.
Cursor Up is OBC (Function number) 88 in decimal.
Convert 88 to hex using Windows Caculator set to Scientific Mode.
88 = 58 (Hex)

All you have to do is edit the hex byte in bold (FF) below to 58,
626A 0000 0000 0002 0026 00FF 8052 0000

I.E.
626A 0000 0000 0002 0026 0058 8052 0000

Repeat the above for all learnt codes.
