The Fidelity slider has 5 presets from Illustrator CC 2014. A new slider preset (most accurate preset) has been added to
help you draw the most accurate path possible. Other dialogs that have the additional preset are the Smooth tool, Brush

Auto-closing paths
When the endpoints of a path you are drawing are in close proximity and within a certain predefined number of pixels
of each other, the path-close cursor (

automatically.
The predefined number of pixels is set in the Pencil Tool Options dialog box > Within field.

You can use the pencil tool to draw constrained or unconstrained straight segments. While drawing a straight segment,
the straight-segment cursor (

Constrained straight segments Hold the Shift key, and then use the Pencil tool to draw straight segments constrained
to 0, 45 or 90 degrees.

continuation cursor ( ) is displayed, click the mouse button and draw another line.
