How to do a Unskipable line

I am extremely new to all this. One question i had was what if i wanted to make a string were there was one ability i never wanted to skip. Lets say Tiger palm after a Blackout Strike. You wanted the macro to chill after the blackout strike until you had enough chi for the tiger palm to go off. how would you write that in the macro?

Thank you for all you guys do. so far from what ive seen this is a awesome community.

Put two hyphons in from of the offending /cast or /castsequence line, then save it. Type /reload and bring up the macro again and it will have turned brown-orange.

So, it would look like this:

–/cast Tiger Palm
