/bind t "party Pulling now!$$PowerTrayExec 0 3"Chains a party message onto a power so your group sees the call the instant the ability goes out. Tanks use it for pulls, healers for emergency cooldowns.
The core of the whole system. /bind attaches a command to a key; the command goes in quotes. Anything you can type into chat, and every internal engine command, can be bound this way.
