Basically my problem is the same as that documented in this case: gis.thinkgeo.com/Support/DiscussionForums/tabid/143/aff/21/aft/5621/afv/topic/Default.aspx
We, too, are converting a 2.0 application to a 3.0 application. However, the solution documented in that other case doesn't work for my users. They are Police Officers and sit in a car with the laptop offset to the right. We need to provide the functionality for one handed use as much as possible. The 2.0 model of clicking a button and then drawing a rectangle to change the extent worked beautifully.
Holding down the control key, while a neat and powerful enhancement, just doesn't work for our customers. Plus it is hidden functionality and isn't obvious to them.
Is there any way to provide 2.0 like functionality as well for TrackZoomIn?
Thank you!
