There's no Start menu. Everything starts from the dock, the bar along the bottom of the screen.
- To open an app that's in the dock, tap or click its icon.
- To open any other app, use Search. Press the Windows key on your keyboard, or tap the dot at the left end of the dock along the bottom of the screen. Search opens. Type the app's name, such as Konsole or System Settings, and tap it in the list.
- To see every open app at once, swipe up from the bottom edge, or press Windows + S.
