Apart from the actual content, web pages often contain fixed parts which repeat on each page throughout a website. The typical repetitive parts of a Wiking page are:
A visually oriented user may ignore those parts, since they are visually distinguished from the main content. They may, however, impose a problem for AT users. Wiking tries to help by a "screen reader friendly" implementation of these parts and by providing additional navigation mechanisms. These may or may not be suitable depending on the assistive technology being used.
- Screen reader driven navigation
Users of modern screen readers may skip the repetitive parts simply – menus and all panels are labeled by level 3 headings and precede the main content. The main content starts with a top level heading. So you can get to the main content by one key-press or jump around menus and panels by repeating a third level heading jump.
- Page navigation links
You will find a set of links labeled "Jump in page" at the very top of the page. The first of them will always get you to the main content, the following will move your focus to the menus, panels and language selection. These links are most convenient for text oriented browsers.
- Keyboard shortcuts
Some of the Shortcut Keys also allow you to jump within the page.
There are several shortcut keys (access-keys) simplifying navigation:
- 1 ... go to the home page
- 2 ... skip repetitive parts (go the the actual page content)
- 3 ... skip to the main menu
- 9 ... enter/leave the Wiking Management Interface
- 0 ... show the Accessibility Statement
Usage in different types of browsers:
- Internet Explorer – Alt + number Enter
- Firefox 1.x, Mozilla, Netscape 7+ – Alt + number
- Konqueror – press and release Ctrl, number
- Opera – Shift + Esc + number
- Safari, Firefox, Mozilla, Netscape, Omniweb (on Mac OS X) – Ctrl + number
Shortcut keys should not be considered the primary means of navigation. Their usage varies from browser to browser and some browsers don't support them at all. In addition, the key bindings are not standardized, so the behavior differs from site to site.
Many assistive technologies implement their own page navigation features. If these features substitute the above commands, they should be always preferred. For example the page content begins with a top level heading, thus it may be possible to get to it using the heading navigation feature of the AT.
Tables of Contents show the hierarchy of the current page content. As opposed to Navigation Menus, they don't refer to other pages, but just to subsections of the current page.
They display a set of links allowing you to jump to a selected section directly. Each section header also acts as a link back to the Table of Contents. This feature may significantly simplify page navigation in longer texts. Give it a try right on this page...
Some pages may use multiple Tables of Contents in different levels of hierarchy. In this case, the back-reference links from section headers lead always to the nearest TOC up in the hierarchy.
Wiking supports serving content in multiple languages.
Selection of the most appropriate language for each user is performed automatically based on the Content Negotiation technique. This technique relies on the language preference settings of your browser. An English speaking user, for example, should have English set as his/her primary language, plus any number of additional languages which he/she understands with their respective precedence.
A selection algorithm is performed on each request. If given page is available in one of the preferred languages, the highest precedence variant is returned to the user. When none of the requested languages can be served, an error page 406 (Not Acceptable) is returned and the user can select one of the available language variants manually.
Besides the automatic selection described below, user can also select the language explicitly from the language selection menu. This menu is displayed in the top right corner of the page (in the default style) when there are several language variants of the current page. When there is just one variant, the language selection menu is not shown. The menu appears right after the main navigation menu in a text browser. Since the set of available language variants may be different for each page, the language selection menu may differ as well. Current language (as well as current menu item) is emphasized visually and marked by an asterisk in a text browser.
If "cookies" are enabled, the manually selected language will be kept as the preferred language for further requests with even higher priority than the browser settings. This feature allows you to override browser settings when you can't modify them, such as in an Internet cafe or at a public terminal. Correct browser settings should still be the preferred solution, however.
Panels are brief information windows, which are displayed by the right hand side in the default style. They usually summarize the most important information from given website. Panels appear unchanged on each page of the site. For example a News panel may display the most recent news with links to more detailed messages within the News section.
Panels can be hidden, using the "Hide panels" link (located above them). This setting is sticky (panels stay hidden for the following requests) when "cookies" are enabled in the browser. Panels can be unhidden again using the "Show panels" link. Of course, when a page doesn't use any panels, these links don't appear on the page.
Users of assistive technologies may want to skip panels, since they are repeated on each page. See the section Moving around the current page for more information.
