For stepping forward and back through a multi-page HTML slide show or
seminar presentation, it's a _lot_ more convenient to use arrow keys, or
other keyboard shortcuts, rather than mouse clicks on buttons --
especially if the buttons appear at different places on the screen on
successive pages, so you have to keep repositioning as well as clicking
the pointer.
I take it there's no provision for accomplishing this using built-in
capabilities of plain standard "vanilla" HTML, without deploying more
complex Java or server-side tools? -- and more generally no way to
accept and process keyboard input for web site navigation using just
HTML alone?
(Not talking about forms and collecting data here -- just navigation.)
If so, too bad -- lots of unrelated computer applications seem to be
standardizing these days on a GUI "pseudo standard" in which Tab moves
the input point from input field to field on screen; CR or Enter accepts
or activates keyboard input into those fields.
In lots of applications the display also accepts and responds to the
Home, End, Page Up, and Page Down keys as well as the 4 arrow keys that
appear on a wide range of extended keyboards.
Would be nice if vanilla web sites could easily use those capabilities
also.
