Embedding 2 key press tasks within rate task

Hello, 

I currently have a rating task as an ongoing task, but the two tasks that I would like to embed involve two separate key presses.

I'd like a participant to press "A" when an animal word occurs, and "L" every 3 minutes. Do I have the tasks embedded properly, or what do you recommend?
