For machines with insufficient power to support smooth motion
through a VR scene, we can provide browsers which allow you to jump
to a new position simply by clicking on where you want to go.
Double clicking would then be reserved for picking things up or
teleporting through a cyberspace hyperlink.

The cursor motion keys could be used for systems without a mouse or
other pointing device. Although it would be quite a challenge to
write a VRML browser for a 512K DOS system!
