(Sorry for the inconvenience)
i3 is a lightweight, tiling window manager. Keyboard shortcuts are provided to open xterms in order to start applications from the command line.
It does provide a panel and on PC-BSD that panel will provide icons for Update Manager, Bluetooth Manager, Wireless Configuration, and Mount Tray.
Figure 6.9a shows a screenshot of i3 running on PC-BSD 9.1.

To open an xterm, use Alt+Enter. Windows do not provide minimize/mazimize or close buttons, so type exit when you are finished using an xterm. To leave the window manager and return to the login screen, type killall i3 from within an xterm.
The i3 Users Guide contains the default key bindings and instructions for customizing i3.
