I will probably end up doing the research on this, but I will be placing the results in this post. Also someone may have already looked into this so that could be a plus. For quite a long time I noticed that the pet taunt button does not turn off taunt, at least on the UF client. I will have to wait till I get home to see if the Titanium client does the same. I guess it is possible something on the opcodes have changed.
Code:
#define PET_STANDUP 10
#define PET_TAUNT 11
#define PET_HOLD 12
#define PET_NOTAUNT 14
