Hashtag syntax (#my-tag) can be used to explicitly assign a Tag to an Object. The tag becomes one of the object’s user tags, stored in its tags attribute, next to its root tag.

Scope rules

  • If a hashtag is the only content in a paragraph (at most with additional hashtags), it applies to the page.
  • If a hashtag is used inside of an item (bullet point, or ordered list), it applies to that item.
  • If a hashtag is used inside of a Task, it applies to that task.
  • If a hashtag is used inside of a paragraph, they apply to the paragraph.
  • If a hashtag is used inside of a heading, it applies to that header.
  • If a hashtag is used inside of a table row, it applies to that table row.
  • If you create a Markdown/Fenced Code Block with a hashtag as language, it doesn’t attach a user tag: the hashtag becomes the root tag of the data objects in the block.

Examples

Paragraph #paragraph-tag-example

  • Item #item-tag-example
  • Task #task-tag-example
name: Hank

Naming rules

Hashtags can contain letters, dashes, underscores and other characters, but not:

  • Whitespace (space, newline, etc.)
  • Characters from this list: !@#$%^&*(),.?":{}|<>\
  • Digits only (e.g. #123)

If you need your tags to contain these characters, you have to surround the tag content with angle brackets like this: #
