I'm very new to the admin side of JIRA, so please excuse this (most likely) very simple question.
I'm working on editing a few of the email templates and I see "keys" being passed to methods and directives (ex. "issue.field.assignee", "common.concepts.key", etc). My question is where do these keys come from? I'd like to know so that I'm aware of the potential keys I can use in the templates.
Thanks in advance!
