We've got a new web part out today, the Lightning Jump Web Part! The idea is, people always need to get to areas within SharePoint such as HR or Expenses, but they don't want to have to navigate through a complex menu structure to find it. Sure Best Bets for Search work, but that's still a two step process of Searching->Navigating. The Lightning Jump web part makes this a one step process by allowing users to enter a keyword, pressing enter, and navigating them off to the Url.
Keywords can be defined, managed, and are security trimmed. The textbox for entering keywords also have nice ajax type ahead functionality.
Check out the screen cast of the web part working here:
