Over the years, Atlassian has worked very hard to tie their products together. The result has been a smooth user experience across systems. Users can work in the system they are currently in, and switch to others via application links.
Confluence and JIRA interact with one another very closely. In one of our live webinars, my colleague, Jan Kuntscher, and I demonstrate JIRA integration in Confluence. Not only do we show standard features, such as individual operations, configurable process lists, and JIRA task list creation within Confluence, we also provide some helpful tips for features that may be unfamiliar to you.
Here's a video of the session:
