Chapter 5.1 LXQt Panel
======================
LXQt Panel is the bar situated at the bottom of your screen by default. The panel contains an application menu, a desktop switcher, a quick-launch bar, a taskbar, a system tray containing applets, and a clock. The panel is highly configurable with a number of settings and plugins.

Usage
------

The application menu allows you to browse and search through available programs; a keyboard shortcut is conveniently available for this. 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). To add a program to quick launch open the menu and find it there and drag it down onto the panel.
