2.4.2 Page Titled
Each page has a unique title element that describes what’s on that page.
2.4.3 Focus Order
When a keyboard user tabs through a page, the order goes from top to bottom and left to right, as you would read the page.
2.4.4 Link Purpose (In Context)
A link’s destination should be clear from either the link text itself or the surrounding sentence context.

Header navigation is not the only way to get around a website; there’s another way, such as on-page links, a sitemap, or a site-wide search.
2.4.6 Headings and Labels
Headings are descriptive of the content that they contain, form labels clearly describe what information is required, and buttons inform the user what will happen when they’re pressed.

There’s visible keyboard focus styling to indicate which element you’re currently focused on.
2.4.8 Location
The user is clearly informed where they are in a set of pages.

It is clear where a link will take you from the link text alone, without having to read the text around it.

All actions that are carried out using a gesture (swiping, pinching, and so on) or drawing, can also be done with a button or buttons.
2.5.2 Pointer Cancellation
