• Ubuntu documentation "Maximize and unmaximize a window" - Valid infos for both Debian Linux with GNOME desktop & Ubuntu Linux.
  • There is ( just ) a close button at the right upper corner of the application window . The Microsoft Windows style buttons minimize button and maximize button are missing .
  • However, there are function keys to maximize a window, and to return to the individual window size:
    • With “Super” key = “Windows key” on modern PC keyboards:
      • “Windows-Key + Cursur-Up” - Maximize window to desktop size. “Windows-Key + Cursur-Down” - Unmaximize window.
    • “ALT + F10” to toggle between maximized window size and unmaximized window size.
• For comparison, the Microsoft Windows design standard:
  • Microsoft Learn "Windows and Messages / About Windows" - “An application window includes elements such as a title bar, a menu bar, the window menu (formerly known as the system menu), the minimize button, the maximize button, the restore button, the close button, a sizing border, a client area, a horizontal scroll bar, and a vertical scroll bar. An application's main window typically includes all of these components”.
