Selecting Options
There are two types of option selection fields.
Round option buttons, also called radio buttons, are used to select options where one option must be selected out of many choices. Click a radio button, or press the Space key, to select an option.
Square option buttons, also called checkboxes, are used when multiple options may be selected independently. Click a checkbox, or press the Space key, to toggle the selection for an option.
