Comparing with the sequences above, you can see that Words 44 and 46 change. For "UP" They change from 0010 and 0020 in one sequence to 0020 and 0010 in the next. Same thing in "Down".
I'm a complete novice at this, but I assume all of these codes toggle like this, since these both sample the exact same bits. This may be a stupid question, but can I just create the twin of one of these on a text editor and append it in to the IR window of the command I already learned? The command would be twice as long, but would have both toggles.
