SUMMARY
When opening the application dashboard, using the global keyboard shortcut or a mouse click, if the search field is focused (which isn't always the case, see bug #510871), it is not possible to use the arrow keys to move the focus to the favorites or application list.

Compare with how the Application Launcher ("kickoff") behaves, where when the search field is focused and empty, using the arrow keys moves the menu focus.

STEPS TO REPRODUCE
1. Open the Application Dashboard.
2. Focus the search field, if not already focused.
3. Use the arrow keys to access the favorites or application menu.

OBSERVED RESULT
Nothing happens

EXPECTED RESULT
The focus should move to the application list or favorites and the user would be able to select an application to launch without searching.

ADDITIONAL INFORMATION
There are few additional navigation issues related to the search field:
1. If the search field is focused, using TAB to navigate to other sections is unintuitive as the Favorites section is the last in the tab order (it should be first)
2. If the search field is not focused when the Application Dashboard launches (which may not be desired anyway - see 510871 - especially if this issue if ever fixed), using the down arrow focuses the last favorite in the first Favorites line, while intuitively one might expect the first favorite to be focused.
