Autohotkey or similar program expert

Function: Assign a hotkey. Press this hotkey to trigger mouse to click at a specific X-Y coordinate and also open a mp3 file stored in C:\ using the default mp3 program. After, will return mouse to original location prior to when hotkey triggered. Will be able to assign any number of mp3 files to be played. For example, if 2 mp3 files assigned, and assuming hotkey is assigned to "F1"... - If user presses "F1" hotkey will click mouse at a specific coordinate, open the first mp3 file, and return mouse to where it was. - If user presses "F1" again, it will click mouse at a specific coordinates, open the second mp3 file, and return mouse to where it was. - If user presses "F1" again for third time, will click mouse at a specific coordinates, open the first mp3 file, and return mouse to where it was. ... I need to be able to have flexibility to setup any number of hotkeys, and will need a tutor show me how to do this rather than to just do it for me. This is an hourly job, and I assume should be a quick and easy job assuming you are an expert at this. Would need to work in Windows XP environment. In your bid, let me know the program you are suggesting we use.
