Calc Guide

To enable sharing, select the box at the top of the dialog, and then
click OK. A message appears stating that you must save the document
to activate shared mode. Click Yes to continue. The word (shared) is
then shown on the title bar after the document’s title.
The Tools > Share Document command can be used to switch the
mode for a document from unshared to shared. However, if you want to
use a shared document in unshared mode, you need to save the shared
document using another name or path. This creates a copy of the
spreadsheet that is not shared.
