Using the Zoom functionality for browsers allows you to enlarge or reduce items displayed. The simplest and most universal way to zoom is to hold down the Control key [Ctrl] or Command key (Mac) and then use the + or - keys or the scroll wheel on your mouse. This will allow you to display items on your browser as needed. Internet accessibility is important even if you are not suffering a visual impairment. Modern web browsers recognize this accessibility need and offer features to increase the size of text and pictures.
