Use ability during cinematic mode?

Use ability during cinematic mode?

How can i order a unit to use an ability when cinematic mode is on?

You need to use triggers of course.
If you are asking how you make the trigger then you need to ask a good triggerer but i think i can tell you how.

Events: must have
Coditions: not necassary
Actions: Unit- Issue order targeting a unit (for example)

Order "Unit" to "Human Priest-Inner Fire (for example)on "unit"

Still i dont know if this is correct, you should ask a good triggerer cause im not very good at making triggers.
