I assume there is a 'like to' here...

EDA_DRAWPANEL::OnMouseWheel would be a good starting point for me.
However IIRC *some* wx version don't have the distinction between
vertical and horizontal wheel (or maybe it was another toolkit, I don't
remember :D)

There is already is the middle button toggle, so IMHO a wheel option
shouldn't hurt.

However I find the best navigation strategy is to zoom out-move-zoom in,
instead of panning: way faster and a lot less movement required.

PS: how lucky you are to have a *bidimensional* wheel on a laptop?!
Usually there are only two button and a single 'wheel' (two button
emulation) on the pricier models:P
