Translate the page using Google Translator
Google Translator provides an easy way to translate web pages into a variety of languages. Simply select the language required from the drop down list.
Keyboard shortcuts control various browser functions and are often a useful and quick way of navigating through a site. For the vast majority of browsers, use your Tab key to navigate forward through links (use Shift + Tab to go backwards), and Enter to activate the link. Many other keys can be used, and will vary depending on the browser and operating system you are using. To find the shortcuts for your browser, follow these steps if your computer is running Internet Explorer or Netscape Navigator on Windows:
- Internet Explorer - Press your F1 key to open the online help and in the index, type "keyboard shortcuts", select the required option and click "display".
- Netscape Navigator - Press your F1 key to open the online help and in the index, type "keyboard".
- Firefox-Mozilla - Press your F1 key to open the online help and in the index, select "keyboard Shortcuts".
Images and alt tags
We have avoided using excessive graphics within the website where possible to ensure quick download times and access to information which cannot be read if in image format. Where images have been used we have added 'Alt' tags - text alternatives so that you will still know what the image is meant to convey even if it does not load or if you've have chosen to browse with the images switched off or you are using an assistive technology like a screen reader to browse the webpage rather than view.
This site uses PDF (Adobe Acrobat) file format for the publication of large and complex documents. Please note that Adobe Acrobat documents can be converted back to plain text using Adobe's Web-based conversion service.
