This is related to my other question: Kate has no window borders, and thus no minimize, maximize, and close buttonsIn KDE, after right-clickin on any window border, or it's entry in the task manager, I can select More Actions and then Fullscreen.Once in this mode, normal window manager commands such as alt-tab and  alt-f4 no longer work.  Moreover, the task bar and everything else remain permanently hidden until I quit the window via the File menu.How do I un-fullscreen a window managed by kwin?
How do I exit full screen after enabling via the right click context menu of kwin (KDE)?
kde;window manager;kde4;kwin;fullscreen
