You can tag events and sections in TimeStory, and use those tags in filters or as a way to include extra information in your timelines. Tags in TimeStory are normally words or short phrases.

For one example, you may want to tag tasks in a project plan by priority: low, medium, and high. Having done so, you can then activate the Event Filter and type #high to see only high-priority tasks, or you can type ~#low to see all tasks which aren’t tagged as low-priority (~means not).

There are two ways to tag things in TimeStory, depending on whether you want the tags to be visible or not.

## Using the Tag List

When working with events or sections, the Inspector offers a Tags field. These tags aren’t visible in the timeline document itself, only in the Inspector. Type in individual tags, using the comma, semicolon, or return key to end each one. To remove a tag, just select it and press Delete.

If you select multiple events or sections with different sets of tags, the Tags field shows all tags used in your selection. If you add or delete a tag, that change is also applied to all the selected events or sections.

## Using Hashtags

Instead of using the Tags field, you can also just type a tag directly into a title or description, prefixed with a # (like a hashtag in social media).

If the tag contains no spaces, punctuation, or other special characters, and doesn’t start with a digit, the # is all you need; for example, #good, #好, and #AssignedToMe. If you want to include spaces in a tag, you can wrap the tag in brackets, for example #[Assigned to Me].

## An Example

To see tagging in action, open the Exploration of Mars example timeline. This document captures the history of successful (and partially successful) missions to Mars, and uses tagging to distinguish the country or agency of origin. For example, type #ESA in the Event Filter to limit display to missions managed by the European Space Agency.
