I am a proponent of binding/unbinding keys in game.
That said, I am not a proponent of poor communication. Guns of Icarus Online is about effective teamwork. You need to utilize specific chats to relay plans and information between players.
Sir, if you do not use crew chat / team chat / in game communication, I canna welcome you onboard.
(I'll still play with you, but don't expect me to like you for telling the other team that we are getting on Front Guns)
