<p>
Use <code>Ctrl-Z</code> or <code>⌘-Z</code> to undo while drawing.
Use <code>Ctrl-Y</code> or <code>⌘-Y</code> to redo what you have
undone. Use <code>Esc</code> to cancel the current sketch.
<p>
The <code>control.undo</code> method works on the current
sketch, removing the most recently added point.
The <code>control.redo</code> method adds back items that were
removed from an undo. To fully erase a sketch, call the
<code>control.cancel</code> method.
