Rotate View Tool
A long-desired feature from other leading digital painting tools is the Rotate View tool, which allows you to rotate the document canvas to make otherwise uncomfortable strokes with a digitized art tablet perfectly natural. Press the R key or click-and-hold the Hand tool at the bottom of the Toolbox and select the Rotate View tool. Click-and-drag on the document until you reach your desired placement. For precision and consistency, you can also enter rotation numerically in the Rotation Angle field in the Options Bar. Click Reset View in the Options Bar, or double- click the Rotate View tool in the Toolbox, to return to normal orientation.
2.) use the MacBook Pro Trackpad (or disable this function with a plugin if you don’t like it)
3.) use the intuos4 touch ring (here are the keys ALT+F13 and ALT+F14 mapped)
Great tool… just figured out that the other way to reset the view is simply to hit the ESC key.
