I'm sorry. I have lost all respect for blizzard now that they've banned for-pay addons and donation solicitation (http://forums.worldofwarcraft.com/thread.html?topicId=15864747207&sid=1). It's one thing to set policies that affect how addons behave in-game. It's another thing entirely to trample on author's copyright. They can block whatever addons they want, but this isn't a zero sum game. For-pay addons and free addons have a synergistic relationship akin to the OSS-commercial software world. I'm deeply disappointed that they don't recognize this fact.

If blizzard wants a macro guide on their site, they can write one themselves or find some other shill to freely give them hours of their time in exchange for nothing.

In the meantime, my guide is available at http://www.wowwiki.com/Making_a_macro

Question on the /click, it can click something in the spell book correct?

Ahh, so I'd be better off sticking the ability on an action bar and referencing the button. Thank you very much for the help and the informative post.

For those wondering what I was doing, I've run into problems inserting Adrenaline Rush into an activation macro for rogue cooldowns. For some reason, no matter what, Adrenaline Rush would not activate. It's finally solved with the /click function.

Here's the Macro:

/click BT3Button60
/cast Blade Flurry
/stopcasting
/cast Berserking(Racial)
/stopcasting
/cast Evasion
/stopcasting

I'm using Bartender3 for my buttons, so it's refering to button 12 of bar 5. As Cogwheel said, use MoveAnything to find the correct frame reference for the /click command. As an additional note, the /click has to come first in the macro, otherwise it will not work.

As a side note, a macro like above normally works as a dumb logic style, aka it'll activate the cooldowns as long as you're clicking it, even if the others are on CD, unlike /castsequence. By adding in the /click, it stops that process, but by setting them all up using /click it returns it to the dumb logic state, but will only activate one at a time. The above activates all with one button press, as long as all are off of CD.

EDIT: Scratch all that, it's not working correctly, only now it's Blade Flurry that's not activating, and I'm still annoyed by it. Check back later to see the results.

Cogwheel...

I am looking to see if it were possible to setup a one button tanking ability....
I want to combine Revenge, Sunder, and Heroic Strike to one button click...
I got it workin fine with /castsequence.
But that doesn't solve my dilema since I want revenge to be my main attack and it isn't always available.
I am looking for something that would be like this...
(My prgramming language knowledge is limited so bear with me)

/cast Revenge;
/if (Revenge = true);
/resetmacro;
/else if (Revenge = false;
/cast Sunder Armor;
/if (Sunder Armor = true);
/reset macro;
/else if (Sunder Armor = false);
/cast Heroic Strike;

I know that is very bad example but I can only relate the programming to a more Java style.
But, I would think that give you the idea of what I am trying to accomplish.

Fantastic information. I am wondering why I can't get this to work though even using /castsequence:

/castsequence Hunter's Mark, petattack

Do I need to specify a target with the petattack? Having seen the other examples you gave I'm assuming I could do something like:

/click PetActionButton1
/cast Hunter's Mark

but only in that order since HM triggers a GC. Am I way off-base here?

petattack is a command, not a spell

/cast Hunter's Mark
/petattack

is what you want. If you don't give it a specific target, your pet will attack the same thing you've got targetted.
