Pen

Use pen to select and interact with content by default - If you have a touch-enabled device and are using a digital pen, by default it starts drawing immediately when the pen hits the document canvas. You can turn off automatic inking and have the pen work as a stylus by default by selecting this option.
Enable the draw and hold ink-to-shape gesture while inking - (Added in 365) After you draw a shape, hold your pen in place to turn your ink into an enhanced shape.
