Radio Buttons have
their own unique way of reacting to <TAB> and the arrow keys.
When navigating using the <TAB> key, if you encounter a set
of Radio Buttons the focus will be placed on the option which is selected.
If neither option is selected, the first one listed will receive the
focus. You may alternate between the options by using the arrow keys.
The <TAB> key
is the main key used to move around the pages. Pressing the <TAB>
key will move the cursor or focus through the controls on a page starting
at the top and moving left to right and top to bottom. All data entry
fields, radio buttons, check boxes, hyperlinks, and buttons are included
in this path.
For example, on the General Claim Information tab, you will enter the
Patient Control Number and Location Information, then click the
key to move to the Client ID field. Once you enter a Client ID, you
may click again to move focus to the Go button. Notice, when
a button has focus there is a dotted box surrounding the button.
The <SHIFT>+<TAB>
key combination will navigate through the controls on a page in reverse
order, therefore right to left and bottom to top. This is useful if
you have pressed the <TAB> key too many times and passed your
desired field or button.
