well its really hard to explain, but i use my thumb as an "anchor" if you will...lol When i shift my hand all i really do is slightly push with my thumb to the left which moves my whole hand slightly to the right. Or if there is just one orange note and not a slew of them just stretch your pinky over there asnd press the orange button! Or you can feel your way down the frets and once your index finger leaves the first green fret and you still feel four frets you know your pinky is on the orange because there are only 5 buttons. It definitely helps to be relaxed, dont grip the guitar with a death grip just chill lol. But really it just boils down to getting a feel for the frets...practice practice practice
