Keyboard control using bluetooth module HC-05

So after reading your response, I came to the conclusion that as per my requirements, I will have to have an application (which I do not have) that will respond to the data sent through the Bluetooth module. But actually, I am looking for a solution to control the keyboard navigation keys using pushbuttons/sensors which can work like normal keys i.e page up-down, cursor movement, etc. So what do you recommend for it.
Thanks
