Sometimes I need an outline/bulleted list which looks like a checklist. Here’s how to create a checkbox bullet in LibreOffice (on the Mac).

• Create an ordinary bulleted list. (Use the bullets tool on the toolbar.)
• Put the insertion point (i-beam cursor) at the beginning of the text of the line with the bullet you want to turn into a checkbox.
• Format > Bullets and Numbering > Options > Select… > Font = Wingdings
• I like the the first empty box in the list. (End of the 5th row on my display.) Character value Unicode F06F.
