MAcros cast the top spell available. then queue the bottom spell. If you hit it again before the bottom {queued} spell can cast, it moves to the second available spell and requeues the bottom and so on. It will always requeue the bottom spell and never move upwards and it will always cast the first available from the top. So you have 5 spells in the macro and spam, it casts 1, queues 5, cancels 5, casts 2 if 1 is down, queues 5, cancels 5, casts 3 if 1 AND 2 are down and queues 5. If one of the earlier spells are ready before 4 is, it will cast that and so on. 5 will go off if you leave a long enough time without spamming or it becomes the top available spell on the list.

You can turn off queueing in the options, but it is seriously bugged at the moment....better off using the clear all queued command...it's in the /list on EQ2Interface forums.

I'd post more, but I am so very sleepy now and I need to rework my setups anyway, so whatever I do now is pretty useless. :P
