How to use any browser to search the DOM (all associated scripts as well) for any keyword

How to enumerate your web app (target) easily for certain keywords -
Load target - any browser pretty much
right click inspect

Once opened goto Sources tab

-> On the left make sure "Page" is selected (not content scripts)
-> right click "top" (right under the page icon you picked)
-> Type in API for instance and hit ENTER

You should see output like you see in the picture below, the browser will search all relevant scripts and info in the source that matches and tell you where it matched those keywords.
