When WWW starts up, it presents the user with a home
document. [to be elaborated how this is selected].
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.
