I often find that I will use the quick-search tool to navigate to issues which I know the ID for (e.g. press / and then enter the key such as JIRA-123).
What I would like to know is whether there is any functionality like this, but something that possibly provides an auto-complete-like UX (similar to the Issue Actions menu loaded with the . key) where I can start typing in JIRA-1 and it will show me the issues matching this and also include the summary field?
