[OpenLayers-Dev] custom zoom-in

[Hans Castorp]

Hi to all,

I'm trying to implement a button outside the map, in order to let users zoomin 
without holding ctrl and dragging at the same time (due to accesibility 
reasons). 

Something like this:
-Click on a button to activate zoomin
-Zoomin activated
-Click and drag to select the area 
-Release mouse button
-Zoomin
-Zoomin desactivated (normal behaviour)

Any help will be welcomed.
Thanks in advance.
