Hello my friends I'm having problems configuring the FT button for shaman healer I don't understand much about macros and I'm not able to do the macros I need for maxdps to heal the party it doesn't change target

You must create a macro in the game, the text of which is written in the FT tooltip.

Only 1 macro it all? and how F1 F2and F5 work sry but i'm new here
