|sword n' board
Any combat maneuver that you can do in place of a melee attack.
For example Disarm states:
You can attempt to disarm your opponent in place of a melee attack. If you do not have the Improved Disarm feat, or a similar ability, attempting to disarm a foe provokes an attack of opportunity from the target of your maneuver. Attempting to disarm a foe while unarmed imposes a –4 penalty on the attack.
Disarm can be used in place of any melee attack (including AoO).
The others that will work (that I know of) are:
The rest take standard actions, and thus cannot be done on an Attack of Opportunity.
