Arduino UNO R3 Hid Keyboard with RN-42

Hello, I need some help with project. I would like to send keypress to my pc using bluetooth hid, usb host Shield and mouse. Main idea is to use mouse connected to arduino to move in pc games. When I go up with mouse conected to USB Host Shield there should be send keypress with bluetooth module to pc with "w" to move foward in game. When the mouse move stops there should be keyrelease. Same thing with moving mouse down (keypress "s"), left (keypress "a"), and right ("d). I would also like to convert mouse leftclick to "c". There could be little buffer to filter out micro movements to avoid shaking. For example register movement if distance is bigger then 1 cm. I have: Arduino UNO r3 Hc-05 with rn-42 firmware USB Host Shield - [login to view URL] Some wireless mouse For now I merge some projects and figure out to send to serial port monitor letters adequate to the mouse movement. I will be grateful for further help with the project.
