Tags are keywords or topics that help you quickly find the notes you want. ## Add a tag to a note To create a tag, enter a hash symbol (`#`) in the editor, followed by a keyword. For example, `#meeting`. You can also add tags using the `tags` [[Properties|property]]. Tags in YAML should always be formatted as a list: ```yaml --- tags: - recipe - cooking --- ``` ## Find notes using tags To find notes using the [[Search]] plugin, use the `tag` [[Search#Search operators|search operator]] in your search term, for example `tag:#meeting`. You can also search for tags by clicking on them in your notes. To find notes using the [[Tags view|Tags view]] plugin, select **Tags: Show tags** in the [[Command palette]], and then select the tag you want to search for. ## Nested tags Nested tags define tag hierarchies that make it easier to find and filter related tags. Create nested tags by using forward slashes (`/`) in the tag name, for example `#inbox/to-read` and `#inbox/processing`. Both the [[Search]] and [[Tags view|Tags view]] plugins support nested tags. ## Tag format You can use any of the following characters in your tags: - Alphabetical letters - Numbers - Underscore (`_`) - Hyphen (`-`) - Forward slash (`/`) for [[#Nested tags]] Tags must contain at least one non-numerical character. For example, #1984 isn't a valid tag, but #y1984 is. Tags can't contain blank spaces. To separate two or more words, you can instead use the following formats: - #camelCase - #PascalCase - #snake_case - #kebab-case
