For example, How to access the system tray using the keyboard? has been flagged as a duplicate of How to access (or switch between) tray icons with shortcut in windows?. The former one has been asked over 2 months later, but has better score and more accurate answers.

Technically speaking, it's obvious that this one is a duplicate. On the other hand, closing it will redirect users to a question with less useful answers.

Should we flag older question as a duplicate if the newer one is of better quality?
