     #show Expolsive Shot
     /click MultiBarRightButton1
     /click MultiBarRightButton2
     /click MultiBarRightButton3

     /castsequence reset=combat explosive shot, null

button      5
     /castsequence Steady shot,
     /cast Explosive shot

This should start with an explosive shot, place the dots, use steady shot as a filler and fire explosive shot when it's up. (You could use the !Autoshot trick mentioned in olipcs link to get the timings a bit better)

Cant wait to try this! So the "null" means its a one time deal? I like it! Was trying to figure out how to apply Hunter's Mark without using a seperate button!

Also, should kill command be in there?
