I have looked at the WoD Macro thread, but I am not quite sure how to setup something like this:

Step 1: 0,1,9
Step 2: 1,2,4
Step 3: 1,3,4

But perhaps I just need to spend some time figuring it out on my own.

Does this mean that the first time I press the assigned key, it tries to do "0","1" and "9" all at the same time?
Then the next time I press the assigned key, it tries to do "1", "2" and "4" all at the same time?
