Navigating this site

This is the target of the <link rel=help ... > tags throughout this site. It describes how the site is laid out, and how <link> elements and accesskey attributes are used in it.

If you have found this page (other than by listing the contents of the directory) then you are probably one of the fortunate few people who use a browser that implements the LINK tag in a useful way, because there are no conventional links to it from anywhere else on the site (or anywhere else at all, for that matter, as far as I know).

The basic structure of the site is defined in the Site Map. All other pages are easily accessible from there, though in some cases via an intermediate page: for example, only recent publications are listed on the site map; older ones can be found by following the Complete list links. A more conversational introduction to the site is the Home Page, which exists also in French and Spanish versions.

Standard targets for <link> tags

The icons displayed by the names of the links are those used by the browser iCab, which at the time this page was originally written (late 2000) appeared to be the only browser apart from Lynx that made any use of <link> tags. However, there have been some improvements since, and Mozilla and the Mac version of Opera are now reported to implement them.

Home

The home link leads from any page to the Home Page of the site.

Contents

In pages that form parts of a related series that have a separate contents page the contents link leads to that page.

First (or Start)

In pages that form parts of a related series following a definite sequence the first link leads to the first page in the sequence; otherwise it is disabled.

Prev

In pages that form parts of a related series following a definite sequence the prev link leads to the previous page in the sequence; otherwise it is disabled.

Next

In pages that form parts of a related series following a definite sequence the next link leads to the next page in the sequence; otherwise it is disabled.

Last (or End)

In pages that form parts of a related series following a definite sequence the last link leads to the last page in the sequence; otherwise it is disabled.

Up

The up link leads to the next page up in the hierarchy. As the hierarchy is not always unambiguous (i.e. many pages can be found in more than one way and hence have more than one "parent") the link may sometimes appear arbitrary.

Index

The index link is not at present used in this site.

Search

At present this link is inactive on this site. However, each page has a search form on the top line.

Help

The help link leads to this page.

Copyright

The copyright link leads to the page containing copyright and similar information.

Author

The author link activates your email application with a new message to me.

Links

The last entry here is not generated by a <link> tag, but, if implemented by your browser, will activate a drop-down menu allowing you to select any <link> defined in the page (including any style sheets).

French or Spanish versions

A few pages on this site exist also in French or Spanish versions. When this is the case links of the following type appear in the navigation bar at the top of the page: ES or FR

The codes used are the standard language codes: ES = Spanish, FR = French, and, if you are already on a French or a Spanish page, EN = English.

Access keys

The accesskey attribute is another useful feature in HTML that has so far been very little used. Browsers that recognize it at all interpret it in different ways. On this site the following assesskeys are used systematically:

For pages that exist in multiple versions,
