Background program to monitor user typing

I need a key logging program that will run continuously in the background and monitor the user typing into an edit box on any program or form. When it detects that the word "email" has been typed it will take action. This will consist of trapping the creation of? the context (right-click) menu. If this event occurs, an option will be added to the menu reading "Complete email". When the context menu is subsequently painted, the option will be visible. If that's not possible, I'll accept a custom context menu with a single option. If the user should choose that option,? the word "email" will be replaced by a pre-defined? email address? (use? any string for test purposes) ## Deliverables This project requires good shell programming skills and I am prepared to pay a fair rate for this. I'm not sure exactly how it will work, but perhaps the background program will look out for WM_CHAR and WM_CONTEXTMENU events.
