Sorry for the empty header: It seems that hitting enter submits the report. I would like to suggest to add a default keyboard binding for accessing the Applications Menu in Xfce. Currently when one loses the mouse (for whatever obscure bug), one cannot do much if anything in Xfce. Providing a keyboard shortcut such as 'ctrl + escape' bound to 'xfce4-popup-applicationsmenu' would help in cases where the mouse is no longer available.
Alt + F1 is set to trigger xfce4-popup-applicationsmenu in current git master branch.
