Choosing points or pixels

Choose points or pixels as the units in your document. Using points will change all numeric values to points, and will affect the nudge commands in the canvas. With a pixel density of 2, nudging layers with the arrow keys will move them 1px or, if points are selected, 1pt (2px). The point/pixel unit setting is remembered throughout the app, and is not saved into the document.
