when I get a trick and apply that on my work, should I say "put it in" or "put it on"?

From a very basic level understanding of your question, I would say "Put it in your Powerpoint" and not "Put it on your Powerpoint", assuming that is what you are asking.

Also what do you mean by a "trick"? I think you are trying to say a new discovery or a new way to do something, but "trick" sounds like you are trying to play a joke on someone.

Feel free to let me know if I have misunderstood you.
