PL/SQL Autocomplete & Examples

Would love to have autocomplete for plsql commands and to show examples (maybe in a pop-up, activated by highlighting a command and pressing some key combo).
Could integrate with a site that already has this info. Also, being able to set the version (e.g., Oracle 11gR2) would be really sweet. Having this integrated into an editor rather than having to refer to *gulp* books, or online resources we be...sublime.
