You Don't know how to play a chord??
Choose a chord from the list, and press "Show" On the left side, you'll see the chord you are searching for.
When you play a note without touching it, there's a dot on the upper row. Notes played on the first fret are then shown on the second row of dots.
The notes are from left to right:
E, A, D, G, B and e.
Strings not to be played are shown with a blinking dot.
To clear the chords, press "Clear"
