A screen reader is a type of software that enables those who are blind or visually impaired to interact with mainstream applications, such as web browsers, on both desktop and mobile platforms.
Screen readers perform two primary functions. First, they provide access to the on-screen display via voice output, a refreshable Braille display or through magnification. Second, they replace the mouse and make user interaction with an app or website more efficient through the use of a robust set of keyboard commands or touch gestures if used on a mobile device with a touch screen. Desktop screen readers read left to right, top to bottom.

Navigating Web Pages with Screen Readers
There are several approaches that you can take to navigate a webpage when using a screen reader.
TAB & SHIFT-TAB
Allows you to move forward and backward through actionable elements including links, form input fields and other controls. Pressing TAB moves forward and SHIFT-TAB moves backward. This is a standard keyboard shortcut in all popular web browsers (Internet Explorer, Firefox, Safari and Chrome).
Displays all of the hyperlinks on the page list form. Keystrokes can also be used to quickly navigate these lists. For example, typing the p key filters for links that begin with “p.” This can be extremely helpful on repeat visits to a website, or when directed to find a specific link on a page.
Page Header Navigation
Screen readers allow the display of all page headers in a list, enabling you to quickly skim sections of a page. You can quickly reach the desired section by highlighting the header in the list and pressing the Enter key.
Enable screen readers to efficiently locate specific regions of a page. They behave similar to page headers and may be used in lieu of page headers. Comcast’s webmail interface makes extensive use of landmarks.
Single Letter Commands:
Offer a simplified method to quickly navigate a webpage. For example, pressing the letter h while reading a page with JAWS or NVDA will skip between page headers. Pressing the letter f will jump between form elements (input fields, buttons, etc.). Pressing ; (semicolon) in JAWS will skip between landmarks.
