Mar 24 2015 : Major Update to Strum Shorthand

Please see http://powerup.ukuleleplay.com/strumming/key-strum-shorthand/ for a major new update to the strumming shorthand. Changes will facilitate a much cleaner / easier to read layout for complex strumming patterns. These updates were necessary for the forthcoming Funk, Blues, Rock and Swing pages on strumming.
