Option buttons (also called “radio buttons”) are small round buttons usually found in groups of two or more.
These may be displayed either horizontally or vertically, depending on the window they are in.
To Select an Option:
Click once on the required option button or option name with the mouse.
An option is selected when a small coloured circle is shown inside the option button. Only one option in a group of related options can be selected at a time. Selecting a new option will de-select the previous option.
