The Pad++ Metaphor (continued)

The above scenario is impossible because we can't read or write at microscopic scale. Yet the concept is very natural since it mimics the way we continually manage to find things by giving everything a physical place. A good approximation to the ideal depicted would be to provide ourselves with some sort of system of `magic magnifying glasses' through which we can read, write, or create cross-references on an indefinitely enlargeable (`zoomable') surface.

Pad++ gives users this zoomable surface. Before we look in detail at Pad++, though, lets clarify what we mean by zooming.

What exactly is meant by zooming?

To illustrate what we mean by zooming, there follows a series of snapshots of a Pad++ session which show how you might interact with a zoomable drawing application.
