Browsing interface
Many hypertext systems use a mouse for selecting information for
detailed exploration. However, I prefer "arrow key browsing" of
information, for the following reasons:
(1) Arrow keys are faster than moving a mouse
(2) Arrow keys are familiar to most computer users
(3) Arrow keys require less physical effort than a mouse
(4) Arrow keys require less hand/eye coordination
(5) Arrow keys are easily learned in a minute
(6) Arrow keys are sufficient for all operations
Having built and used several hypertext systems with hypertext
jumps exceeding 120,000 links <link10>, I do not believe a mouse is
necessary or beneficial for text-based hypertext applications.
Opinion -- While 90 % of all information is visual, 90% of
======= recorded knowledge is in textual formats ...
meaning arrows are best for textual formats.
PS: A experienced developer can do 4000 screens and 15,000 links
per month using our approach and construction tools. <link54>
