Go to the Next Unread Message Quickly in Mozilla Thunderbird or Netscape

I'm often browsing through all my new, unread messages, deciding which needs to be answerd immediately and what can wait. Fortunately, Mozilla Thunderbird, Netscape and Mozilla provide a handy keyboard shortcut to open the next unread message quickly.

To go to the next unread message in Netscape:

• Hit N (that's a lowercase 'n', not Shift-N; think "next").
