Macro for a tank provoke may look something like this:
/party (Provoke used) -> <t>
/ac "provoke"<t>
AC are actions. So anything involving any of your skills. This can go from attacks to skills such as Addle or Provoke.
PAC are Pet Actions
<t> represents the enemy you're currently targeting.
<me> represents it being used on you and such
<p1> <p2> and so fourth represents the slots in your party configuration set up.
Some people have tanks at the top > healers second > dps third or vice versa, etc.
This will show you every type of macro in the game in terms of tabs:

If you have any specific macros you're trying to make, let us know! The only thing I really advise it not doing your rotation skills as a macro. Even with the delay of /wait 1 or etc, this can cause dps loss. So don't macro those lol.
