LibreOffice 7.5 Help
Every docked window has an icon to control the display properties of the window.
To show or hide a docked window, click the icon.
You can click the edge of a hidden docked window to open the window.
The docked window closes automatically when you move the mouse pointer outside of the window.
Multiple docked windows act as a single window in AutoShow/AutoHide mode.
If you drag an object over the edge of a hidden docked window, the window opens in AutoShow mode.
