Link - Implementing a selection box for Google Maps - via PubSub

An enterprising Google Map “hacker” has created some code that will allow you to zoom in via drawing a window on the screen. To zoom into an area, click the ‘z’ button and move your mouse to select an area, then release ‘z’. It works pretty well and I suspect we’ll see many Google Maps “mashups” to use this. The Google Maps API continues to impress me on how easy people are able to take advantage of it.
