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
