This website incorporates some options to assist users who are visually impaired or have difficulty in using a mouse.
Text size
At the top right of every page there is a button labelled 'Larger Text'. Clicking this button will increase the text size. Also the button label will change to 'Normal Text' which, as the name suggests, when clicked will return the text to normal size.
It is also possible to use your browser's built in tools for changing the text size. Indeed, the latest browsers have a function for 'zooming' the entire page making any graphics larger as well. This function is often activated by Cntrl-+ and Cntrl-- (i.e. by pressing the Control and Plus keys together for zooming in, and the Control and Minus, or Hyphen, keys for zooming out).
Tip: Using a combination of the above you can zoom in so that the main text area fills your screen with very large text which does not have to be scrolled from side to side.
Navigation using the keyboard in Internet Explorer
To quickly move to the hyperlinks on any particular page please use the following keys:
For hyperlinks on the left-hand navigation panel press Alt-L.
For hyperlinks in the the main text area press Alt-M.
For hyperlinks on the right-hand navigation panel (where applicable) press Alt-R.
For hyperlinks at the foot of the page press Alt-F
After pressing one of the above key combinations, next press the Tab key to move through the available hyperlinks one by one. Having selected the link you require, pressing Return will then display the page to which the link refers.
To return to the previous page(s) press Alt - left-arrow, or to go forward through recently viewed pages press Alt - right-arrow.
To scroll the page up or down use the up and down arrow keys.
