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>Navigate the map in one of three ways:
|
|
<ul>
|
|
<li>Click on the named links to zoom and pan</li>
|
|
<li>Use following keys to pan and zoom:
|
|
<ul>
|
|
<li>+ (zoom in)</li>
|
|
<li>- (zoom out)</li>
|
|
<li>up-arrow (pan north)</li>
|
|
<li>down-arrow (pan south)</li>
|
|
<li>left-arrow (pan east)</li>
|
|
<li>right-arrow (pan west)</li>
|
|
</ul>
|
|
</li>
|
|
<li>If access keys work for links in your browser, use:
|
|
<ul>
|
|
<li>i (zoom in)</li>
|
|
<li>o (zoom out)</li>
|
|
<li>n (pan north)</li>
|
|
<li>s (pan south)</li>
|
|
<li>e (pan east)</li>
|
|
<li>w (pan west)</li>

</ul>

This is an example of using alternate methods to control panning and zooming. This approach uses map.pan() and map.zoom(). You'll note that to pan, additional math is necessary along with map.size() in order to set the distance to pan.
