The menus

The main menu

The main menu under the banner allows you to access the main pages and categories of this blog.

The quick access menu

In the banner, just before the search field, a quick access menu is proposed. The first two links of this menu – entitled “Go to content” and “Go to categories” – allow you to position yourself directly at the level of the main content of each page and at the level of the list of article categories. These links are particularly useful for people who navigate by keyboard or cell phone. This quick access menu also allows you to go directly to the help page (this page).

The footer menu

At the bottom of the page, the footer menu allows you to access additional pages such as the “Legal Notice” page and the site map.

Ariadne's thread

On all the pages of the site, a breadcrumb trail is displayed at the top of the main content.
This breadcrumb trail allows you to locate yourself in the tree structure of the site.
It shows you the path taken from the home page to the current page, and also allows you to go back up the site tree through links.

The site map

On all pages, a site map is accessible via a link in the footer menu.

This site map allows you to have an overview of the site’s tree structure and to directly access the article, category or page of your choice.

The search engine

On all pages, a search field is available in the banner. When you make a search, the search engine lists the articles and pages of the site that best match your expectations.

Features offered by your browser

In addition to the aids available, the site has been designed to allow your browser to take full advantage of its own features.

Enlargement of the font size

On all the pages of the site, you have the possibility to enlarge the size of the characters. If you are on a PC, use the key combination Ctrl + + to enlarge the font size. The key combination Ctrl + allows you to reduce the size of the characters. Successive presses of these keys allow you to increase or decrease the font size in increments. Note also that the key combination Ctrl + 0 (the number “zero”) allows you to return to the default text size. Mac users, simply replace the Ctrl key with the Cmd key in the above mentioned combinations to perform the same actions.
