I think you will find that two-finger touchpad scrolls will generate standard scroll messages: WM_MOUSEWHEEL, WM_VSCROLL or WM_HSCROLL as appropriate. Should be easy enough to test.
Go to the next node in Properties named Debugging, and change the Command entry from $(TargetPath) to the same path as you previously changed, followed by $(TargetFileName); you may need a backslash in front. But all of this begs the question: why? You are just storing up trouble for the future by not sticking to the defaults.
