As far as I can tell, the keyboard access does not depend on a screen
reader; I can also arrow to them without a screen reader. (Sidenote:
Visually, the apps list appears as set of big icons, not as a menu.)

Keyboard access to the items on the apps page is covered by checkpoint 1.1
in the User Agent Accessibility Guidelines (UAAG) 1.0
<http://www.w3.org/TR/UAAG10/uaag10.html#tech-device-independent-ui> and
by guideline 2.1 in the current draft of UAAG 2.0:
These guidelines require that keyboard access is supported but they don't
dictate which keys should be used.
For comparison: many browsers support the TAB key to navigate through
links and form elements, but Opera uses the key 'A' to cycle through
links. As far as I know, both methods are valid ways to provide keyboard
access to links.

Does this help?
