Meanings of the icons

Icon	Description
	Add page to Favourites This icon is available only in Internet Explorer. This is the quick way to add frequently used websites to your favourites.
	Retrieve messages in RSS format RSS is a message exchange standard. It stands for Really Simple Syndication. RSS is used to provide content, particularly news, from websites in machine-readable form. An RSS file consists only of the "content", in other words the actual text of a page without the design and layout elements. An RSS file can therefore be read on any platform. Offerings in RSS format are also called news feeds or RSS feeds. Here you can find more information on RSS.

	Print current page This prints out the contents of the current page. The side columns are not printed.
	Adjust text size You can resize the text in several stages. This setting then applies to all the pages. For the setting to be saved you must allow cookies on our pages. If necessary you can also control the display size from your browser (zoom function or text resize setting in the browser).
