Changing text size

If you find that the default text size is difficult to read, you can choose a more suitable size by zooming the page or increasing the text size. In most modern browsers zooming is available by holding the Ctrl key and pressing the + (plus) key to zoom in. You can also use Ctrl and - (minus) to zoom out or Ctrl and 0 (zero) to reset to the default size (Apple users use the Command  key in place of Ctrl).

Some browsers may also allow you to increase the text size independent of the other elements of the page. This setting is generally found in your browser's Tools/Preferences/Options area.


Where a hyperlink takes you to a location other than a page within this website, the action of the link is communicated through the following icons:

  • link opens in new window  Signifies that the link opens a third-party website in a new browser window.
  • document opens in new window  Signifies that the link opens a document in a new browser window.
  • opens email message  Signifies that the link opens an email message using the email software specified in your browser settings.

Where the hyperlink is to a file, the type and size of the file is indicated in brackets immediately following the link. For example, [PDF 120KB] indicates that the link is to a PDF (Portable Document Format) file and is 120 kilobytes in size.
