I am building a dictionary(translator) . My dictionary is completed, now I want to add some feature to it. I want to add a feature that once the user highlight a word in any application, afte 2 seconds which the mouse is IDLE my dictionary automatically COPY and PASTE the highlighted word into the dictionary. I know, I have to use MOUSE IDLE API, COPY API( CTRL +C) and PASTE API( CTRL +V). But I don't know how can I do it and what should I study about. I want to pass the key automatically. Do you have any Idea about my Case?
