Bash Auto-Completion Doesn't Work With XFCE 4.10

If your bash auto-completion is not working with XFCE 4.10, make sure that the tab key isn't mapped to something else. Access the Keyboard configuration by navigating to

Application > Settings > Window Manager > Keyboard

By default, the "Super + Tab" shortcut is mapped to "Switch window for same application". Clearing that setting will fix the bash auto-completion issue.
