Shortcuts using JIRA
At Terracotta, we use JIRA for issue tracking (see here at jira.terracotta.org).
Today, I stumbled on a really nice feature. On a whim, I thought "I wonder if they implement shortcut (hotkeys)?". So I tried it out - sure enough "Ctrl+e" edits a JIRA issue, and "Ctrl+s" saves it. NICE!
+1 for Atlassian.
