If you try to TrackZoom by holding down the Shift key, while in any DrawMode other than "Normal", it does not work. In Polygon mode, it seems to put you in a free drawing mode, while in the other modes it doesn't change anything.
Track Zoom in all DrawModes
Rob,
I didn’t notice this and thanks for point it out :) I’ve written it down and we will see whether we will support this feature in the future release.
Thanks!
Ben
