The Keyword Highlighter plugin enhances the note-taking experience in Obsidian by allowing users to highlight specific keywords for better organization and readability. Ideal for researchers, students, and professionals, the plugin makes it easy to locate important information within large volumes of text. Users can highlight keywords by typing them followed by a colon (e.g., TODO:), with predefined options like TODO, ADD, and FIXME. Additionally, custom keywords can be added with customizable font and background colors, edited for flexibility, or removed as needed. This feature ensures clarity and focus in your notes, improving productivity and information retrieval.
