Function
Home document
When WWW starts up, it presents the user
with a home document. [to be elaborated how this is selected].
Presentation
Documents are presented in one of three
ways:
- as formatted SGML-source text, by WWW itself, with anchor
display and selection possible,
- as text or PostScript, by WWW itself, with anchor display
and selection possible,
- as any other format of document by a foreign program which
understands the format, but with no anchor display (and hence
no selection possible).
Navigation by link
Only tail anchors are visible.
Choosing the tail anchor of a link (by double-clicking or typing
a number etc.) WWW traverses the link and displays the target document, with
the head anchor highlighted (if this is not the entire document)
Navigation by Search
A document which is an index will
have an associated search panel (or prompt) where the user has to
type search keywords. Confirmation of the keyword set (by typing
return to the search panel) will lead to the search being done
and the resulting list of data being displayed as a new document.
