The document describes a method for creating fill-in-the-blank questions in Obsidian to enhance memory retention. It explains the principle of using community plugins to alter the display of fill-in content, such as masking or blurring. The key plugin mentioned is "Masking Type," with settings that allow users to designate bold, italic, or highlighted text as fill-in-the-blank options. The fill-in effects are visible only in reading mode, while editing mode is used to create the questions. Users can easily toggle the visibility of the fill-in content by clicking on the masked areas.
