How to implement common navigation elements in an accessible way.
Keyboard Navigation
You can navigate through a web page's interactive elements by pressing tab to jump to the next item, and shift + tab to go back.
Try it out on a site, you should see the target element's focus style, indicating that it's selected.
For links, the url it points to will be in the bottom left corner of your browser.
Press space to scroll down a page, but keep in mind the tab selection will not move, so if you press tab now, it will scroll back to focus on the current target.
There is also carat navigation for navigating like in an editable document.
Power users may like using a plugin for VIM shortcuts, but that's another thing.
Skip Links
A skip link is an invisible link that lets you jump to part of the page and trigger keyboard focus there.
They are commonly used at the top of pages to skip past the main navigation.
There is one on this site, reload the page and press tab and you should see it.
