HyperRez: Right/Left arrow <sum02 1 8>
==========================
The Right arrow, which executes highlighted hypertext jumps,
expands displayed details. The Left arrow, which returns to
previously selected jumps, collapses details.
To help users systematically explore a body of knowledge, HyperRez
remembers each of the previous screens along with the associated
highlighted jump. This automatic "bookmark" <link35 1 13>
capability is limited to hypertext jumps of 64 levels deep.
Hypertext systems should include the following properties:
Key
Points (1) work without knowledge of the search goal <link32>
====== (2) work without knowledge of the subject <link33>
(3) work without knowledge of the access technology <link34>
The HyperRez command interfaces (mostly Up/Dn/Right/Left keys)
aid these three requirements. Success with points (1) and (2)
depend on rapid responses to a selected command. Point (3)
depends on matching operating keystrokes to user-intuitive actions.
And???
====== Point (4) - the developer must make all jumps predictable. <link53>
