Reaction Command

A Reaction Command is a feature introduced in Kingdom Hearts II, intended to extend the level of combat. By pressing the triangle button at certain moments in battle (or occasionally outside of battle), Sora will perform a specific action, which is indicated by the title of the command. These reactions are mostly combat maneuvers that are used to gain the upper hand on enemies, though they are also used to talk to people and open chests. Occasionally, some reaction commands must be completed in order to end the battle. Interestingly enough, almost none of the reaction commands require that you press triangle the moment it appears; if you cannot press the button at the right moment, you will suffer no penalty by rapidly pressing triangle until the command is initiated. There is only one command in the entire game that requires you to react in time.

Talk
Used to talk to NPCs. Sora can talk to his party members at certain points in the game, when they are not moving together with him. One instance is at the Altar of Naught in The World That Never Was.

Open
Sora or Roxas uses the Keyblade and/or the Struggle weapon to open chests.

Skateboard
Mount or dismount a skateboard.

Reversal

 * Sora (or Roxas) quickly dashes behind the enemy, confusing all Dusks and Creepers in the immediate area for a short time. Can also be used against Twilight Thorn's and Xemnas' thorn attacks.
