[OpenLayers-Users] Re: How to add a Keyboard handler to a map?

[Jan Wedel]

Hi Sasha,

thanks for your reply.

Doesn't that interfere with OpenLayers.Control.KeyboardDefaults which I also
use? I means, if you hijack the document handler, OL is probably unable to
handle other events, isn't it?

Thanks!
