Help and usage tips
Here are a few tips that will make it easier to use our website. Many of these tips are applicable to all websites.
This website uses style sheets (CSS) to make web browsers format each page for printing automatically. There is no special "printer friendly" version of each page. All you have to do is use your web browser's built-in print function.
On the printed page, menus and other elements that are not related to the main content are removed, and the font and text size are changed to be more suitable for printing.
If you would like to see what the printout will look like before actually sending it to your printer, select "Print preview" in your web browser or the print dialog.
This website specifies text size in a way that makes it possible to change the text size with the built-in functionality of all web browsers. The method for changing text size varies depending on which web browser you use. If you do not know which web browser you are using, the name is usually displayed at the top of the window or in the menu bar.
There are too many web browsers for us to be able to explain how to change text size in all of them. If you are unsure of how to do it in your web browser the information should be available in the browser's documentation or help system.
To increase/decrease the size of both text and other content proportionally, consult your web browser's documentation, but a commonly-used shortcut key combination on PC to increase or decrease the size of everything on the page is the CTRL key and + and CTRL key and - respectively, or Cmd and + or - on Apple computers.
Most internal links on this website open in the current window or tab. If you want to manually open a link in a new window or a new tab, you can right-click the link and select "Open Link in New Window" or "Open Link in New Tab".
You can also hold down a key while clicking the link to open it in a new window or tab. Which key to press depends on your web browser and operating system, but the most common ones are Ctrl in Windows and Cmd on Apple computers.
To make it quicker to navigate to the top of the page, a 'scroll to top' button is displayed in a fixed position the bottom of the page.
