If any shortcut key is typed don't activate typeaheadfind(-like) systems.

Reader is expecting an entry to open, an entry to start or an prev/next entry to open.

If you're at the top of the list k, or an empty listing v/s (open/star) will trigger typeaheadfind.

To keep in par with Google Reader, setting 'active = true' if any shortcut key is initially typed will cancel the default action.
