Hi Danny, it kind of sounds like you're talking about zooming with the pointer inside of a viewport without having a keyboard available?

So the difficulty with that is that by default clicking inside the viewport with no modifier keys works to select objects or place points or drag construction lines while in a drawing command.

If just clicking inside of a viewport with no modifiers did zooming instead of that, then how would you select objects or pick points?

There has to be something that tells MoI that it should do different actions - by clicking on the view toolbar icon you're telling MoI to do that.

In the future possibly multi-touch would work for being able to control a zoom in the middle of the viewport without needing to use the zoom button. But current TabletPCs are not set up with that capability I don't think.
