Verify that the functionality provided by the 34 links, form controls, elements with event handlers and/or embedded applications is operable through the keyboard.
All functionality provided by the interactive elements on the page must be operable through the keyboard interface.
Many users are unable to use the mouse, either because of visual impairments, which make it difficult or impossible for them to see the pointer, or motor skill impairments, which prevent them from being able to accurately position the mouse pointer.
This requirement is not intended to discourage support for mouse behaviors, but rather to make sure there is an equivalent way of using the keyboard for all interactive tasks that can be performed using the mouse.
The recommended and most efficient way to include keyboard support for interactive elements is to follow computing platform conventions. This will make it it easier for all users to benefit from keyboard support, since the keystrokes and shortcuts will be easier to discover and familiar to the greatest number of users.
Touch typists often prefer keyboard commands over mouse actions, especially for frequently performed operations, since they are much more efficient from a hand motion perspective.
Information about the element associated with the result.
The information typically includes the tag name, accessible name or other information related to the rule requirements.
"Page" means that the result applied to the page. For example, the rule "One main landmark on the page" is a page level rule.
The element position is based on the DOM order of elements in the page.
The element position maybe useful in helping to locate a specific element on the page evaluated (e.g smaller numbers are typically toward the beginning of a page and larger numbers typically toward the end of a page).
Element position 1 is the first element.
The highest element position is the last element.
Element position values for most rule/page results will not be consecutive since a rule only applies to a sub set of elements found on a page.
