callback for twebbrowser delphi

I was wondering how i could make a callback function for the twebbrowser in delphi. I want it to recognize which input or edit box i am clicking in with the mouse..... any ideas?

As requested, hereby the update of the question, the user workflow. The user would 1. select the inputfield on the twebbrowser by mouse. (the program would see what the information is about this inputfield(value, id, etc.....) 2. fill in the field with prefered information (name, password, whatever really)

At the same time this text is linked back into a memo box. That whould be the start, if i understand this it would be a good b开发者_如何学编程eginnning.
