Access Keys Navigation removal

[Francesco Ariis]

Hello everyone,
    today I wanted to take a stab at this bug

    https://bugs.kde.org/show_bug.cgi?id=117576

But upon cloning Falkon's development version, I found this commit

        Remove AccessKeysNavigation plugin

Is there any reason the plugin was removed? Can I help getting
it back?
