The application menu allows you to browse and search through available programs; a keyboard shortcut is conveniently available for this and is set to :kbd:`Alt +F1` by default. The desktop switcher allows you to switch to another virtual desktop, allowing you to keep your workspace organized. The quick launch bar allows you to conveniently launch your file explorer (PCManFM) and web browser (Firefox).
