hold l1 and use up/down on the d-pad to go through that list.

As fol macros other than utility(i.e. message and do something) and crafting you should avoid them during gameplay. They are not helpful. Especially as a tank you will at times be doing Heavy swing on target1 while finishing Skull sunder on target 2 and once you get it butchers block on target 3.

Or even when it comes to tank swap provoke and then then using a readied butchers or skull sunder to get a decent hold on the mob.
