To manage a list of tasks, or to-do items, you can use hashtags (#) in block diagram labels and comments only. A hashtag followed by text is called a bookmark. When you add a hashtag to a block diagram comment, LabVIEW detects a bookmark and bolds the bookmark tag to distinguish it from the rest of the text, such as #rewrite algorithm.
Use bookmarks to identify incomplete code that needs further development. To find all bookmarks in your application, select View»Bookmark Manager to display the Bookmark Manager window.
See our HSE guide on selecting hashtags.
