Spell Shortcuts
Right click on an empty shortcut box. In the large box put /cast Spell Name [eg. /cast Defensive Wind]. In the title box above give it a name, eg Wind. To the right of this there is a key binding box, click on Set, press the key you want to bind that spell to, then save. You dont have to bind a key, can just click on the shortcut box, but having commonly used shortcuts bound can be very useful.
You will always change to a fully defensive stance if hit while casting.Brilliant really as you will take less damage than other stances. Change stance afterwards if you want by clicking on the attack icon of choice, defensive,normal, bloody etc, or make another shortcut and bind it eg /attack bloody.
