The first macro

1. calls the second macro which releases some playbacks
2. calls the third macro which clears some highlights (i.e. makes those handles not highlighted)
3. fires another playback
4. sets a specified playback handle to highlight

1. make this macro available

Essentially this is an approach to set handles to mutually fire and highlight but would require a lot of predefined handles and macros. It is more a snippet to show how some functions can work together.
