On the 770 you were able to toggle the onscreen thumb keyboard by pressing the 'rocker' key, ie the center of the d-pad. This does not seem to work on the n810. Pressing on the input area with a thumb or pad of finger does nothing either, regardless of 'stylus input method' settings in Control Panel.

I'm wanting to assign a hardware key shortcut to open the onscreen thumb keyboard. How is this possible? Via gconf? Or DBus? Or...? hildon-input-method call? Anybody with a little coding experience that could point me in the right direction?
