The \acronym{HUD} (heads-up display) is a new help feature introduced in Ubuntu 12.04. This is a keyboard-friendly utility to help you find commands, features, and preferences embedded deep within the menu structure of an application. \screenshot{02-HUD-message.png}{ss:HUD-message}{The HUD (heads-up display) shows application-specific help information based on your general input.} Activate the \acronym{HUD} by pressing the left \keystroke{Alt+F2} keys on the keyboard. If you want to search a menu item such as creating a new message in \application{Thunderbird}, then just type \emph{message} in the \acronym{HUD} and the option for composing a new email message will come up in the list of matching results. You can press the \keystroke{Enter} key to active the command. \marginnote{The HUD feature may not be available in all applications as this is a new capability in Ubuntu 12.04. Your mileage may vary!} The \acronym{HUD} works for almost all applications that are natively installable in Ubuntu; it also works for some applications running under wine. \marginnote{\acronym{WINE} is an acronym for Wine Is Not an Emulator. It allows you to run some Windows-based applications in Ubuntu. Discussion of how to use WINE is beyond the scope of this manual, but it is worth checking out if you need to run Windows applications under Ubuntu.}
