How to find connection between in-game strings and triggers?

Can someone please explain me how I can indentify which script triggers a specific string from the Strings_ENG_US.package file? Is it possible to track this information?

For example, how can I create a list of all strings related to loading screen tips and their corresponding keys? Or if I want to create a list of strings related to a specific interaction with an object, how can I do that? 

If you played Sims 2 you have to remember the Tree Ring from Bon Voyage DLC where you count the rings and different messages pop-up on the screen and tell you the history of that tree. 

Good old days... where was I? Oh, right, I want to do something similar and need your help with tracking and replacing those strings.

Thank you.
