// Configure button mapping
// ----------


// Wait for button press
// ---------------------
/* Loop or timer: There are basically two ways to do this. With a while() or for() loop, or with a
   timer. The downside with the while() or for() loop is that there is no way to stop it if the user
   should select to configure another button while we are still in an old loop. What will happen then
   is that we start another parallel loop (at least in Windows) that blocks the old loop. And our only
   option to wait for the old loop to finish is with a new loop, and that will block the old loop for as
   long as it's going on. Therefore a timer is easier to control. */
