You may choose to press your 'tab' key to navigate down through the buttons and links on this web page. Conversely, if you hold down your 'shift' key while pressing the 'tab' key, you will be able to navigate back up through the web page in reverse.
When a tabbed-to button or link has a dotted, aqua border surrounding it, you can press your 'enter' key, and that will mimick the 'clicking' of that same button or link using your cursor and mouse.
And any time you wish, you can 'click' on (or navigate to via 'tabbing') the 'TS' button on the left-hand side of your viewport, that will open up the 'Tabbing Stats' popup window, and you will be able to moniter the status of accessibility features
that have been incorporated into this web page.
This web page is printable.
