Questions and Answers
Nearly all elements can be given focus, and have their focus order changed using the 'tabindex' attribute. Elements on a page will be given focus in the order of their tab index. W3 Schools has a great explanation of tabindex here.
To navigate a website with the keyboard, you can start by hitting the tab key. You should see an indicator on the element that has focus. If it is a link, you can hit enter to go to it. While going forward through the tab keys is done with tab, going backwards can be done by hitting the shift key in addition to the tab key. When it comes to various input elements (radio buttons, select boxes), the arrow keys can be used on them once the element has focus.
