Slap labels on Jira tickets so that you may then search against the labels and generate a list of tickets that have the labels.

At a particular ticket, the "Labels" setting under "Details" at the top of the ticket will allow you to type in a magic string for a label. Let's say our label is "YakShaving" and we want to add it to five tickets. Well, we just type in the string on the first ticket and then we will be able to use that string to find the label on subsequent tickets. At the left where it says Backlog, Active sprints, Releases, Reports, Issues, Components go to Issues then click "View all issues and filters" at the upper right and finally "Advanced" at the upper right to use JQL like so to make a list of the tickets with the labels:

labels = YakShaving
