Repro-Steps:
Launch the React Native Gallery-Preview app.
Navigate to the 'Expand menu' button and invoke it.
Now try to navigate in between all the buttons <Home, All samples, Basic input, etc.> present in left navigation bar
Now observe the keyboard behavior.
Actual Result:
There are lot of buttons <Home, All samples, Basic input, etc.> present in left navigation bar and they are navigable using tab key. User needs to use lots of 'tab' keys to come out of the left navigation bar

Expected Result:
Arrow key navigation should be defined along with the count&position, and <expand/collapse> state for the buttons (Home, All Samples, Basic Input, etc.) present in the left navigation bar.

User Impact:
Users who rely on keyboard might feel confused if tab navigation is defined for all the buttons <Home, All samples, Basic input, etc.> present in left navigation bar
