TaskPaper allows you to create tags by typing @ followed by a tag name. You can also include an optional value after the tag like this: @mytag(my value).

The new feature is that TaskPaper now understands lists of comma separated values. For example you can now type @job(jack,jane) and TaskPaper understands that there’s a list of values associated with the tag. When you click on “jack” your lists will be filtered to show all tasks where “jack” is listed on the job.
