"""
MacroPad HID keyboard and mouse demo.

TODO: update all the keys in order to give them fully functionalities.
TODO: quick fix for special characters: use US characters that will be mapped into ITA: _ becomes ?

The demo sends "a" when the first key is pressed, a "B" when
the second key is pressed, "Hello, World!" when the third key is pressed, and decreases the volume
when the fourth key is pressed. It sends a right mouse click when the rotary encoder switch is
pressed. Finally, it moves the mouse left and right when the rotary encoder is rotated
counterclockwise and clockwise respectively.
