JAB: nvda does not interpret Fxx and Control keybindings correctly

[rpaquay]

Repo steps:

• Install Android Studio 2.2 Preview 3 (or later)
• Run Android Studio and nvda
• Create an empty project (or open an existing project) to get to the main IDE window
• Select the "Build > Make Project" menu item

Result:

• nvda speaks "Make Project Ctrl+"

Expected:

• nvda speaks "Make Prokect Ctrl+F9"

This happens for all menu items that are bound to Fxx keys.

This also happens for all menu items that are bound to control keys, for example, selecting the "Navigate > Back" menu item results in nvda speaking "Back Ctrl+Alt+%" instead of "Back Ctrl+Alt+Left".

The reason is that nvda does not handle the modifiers ACCESSIBLE_FKEY_KEYSTROKE and ACCESSIBLE_CONTROLCODE_KEYSTROKE returned by the getAccessibleKeyBindings API.

@jcsteh: Since this can be an annoying bug and there's already a pr, would you mind a p3?

There was a partial implementation of this in PR #6082. It was closed because we lost contact with the author, some small changes were required and further testing. Anyone interested may take this on.
