Final answer:
The Tab key and Enter key are used for accessible website navigation.
Step-by-step explanation:
The two keyboard keys used to provide accessible website navigation for persons with disabilities are the Tab key and the Enter key.
The Tab key allows users to navigate between interactive elements on a web page, such as links, buttons, and form fields. Pressing the Tab key moves the focus from one element to the next in a logical order.
Once the desired element is highlighted, users can activate it by pressing the Enter key. This is particularly useful for individuals who may have difficulty using a mouse or touchscreen.
