LibreOffice 7.5 Help
Anchors the selected object so that it always remains on the current page.
Objects with this anchor can be positioned in relation to the entire page or in relation to the page’s text area.
The position of the anchored object on the current page does not change as content and pages are added or removed from the document.
The current page remains in the document, with its current position in the sequence of pages, as long as the object is anchored to that page.
The anchor icon is displayed at the top left corner of the page.
