thanks to all the contributors who helped put this together. I'm not exactly sure of what's going to happen with this, but for now, at http://openlayers.org/dev/doc/examples.html you can see links to all the examples *with descriptions*. Hooray! git-svn-id: http://svn.openlayers.org/trunk/openlayers@5362 dc9f47b5-9b13-0410-9fdd-eb0c1a62fdaf

<p>Feature digitizing is in freehand mode by default. In freehand mode, the mouse is treated as a pen.
|
|
Drawing begins on mouse down, continues with every mouse move, and ends with mouse up.</p>
|
|
<p>To turn freehand mode off, hold down the shift key while digitizing. With freehand mode off, one
|
|
vertex is added with each click and double-clicks finish drawing. Freehand mode can be toggled on and off
|
|
at any time while drawing.</p>
