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.
