As the old saying goes "If it works, then modify it to make it better".
I had a play with the usb keyboard interface I am using to get joystick control for my machine. The thing I was missing was feedrate control for jogging so decided to add some.
The initial jog speed is 10% of full speed after the machine is homed which is a bit slow. I have added buttons to map the keys for 50% and 100% speed override to give me much faster jogging speed. I also changed the orientation of the controls to make it easier to hold and use. ( No wireless though )
