The "3. Editor Find & Replace" feature added to Confluence 4.1 could really use the addition of (optional) support for regular expressions in the "find" term, and back-references in the "replace" term.
Similar support is available in JSPWiki, and allows complex search/replace to be done on pages.
Make all bullet list entries bold:
Find (regex): ^(* )(.+)
(assumes backreferences to capturing groups are made using backslash, JSPWiki uses "$")
A screenshot using the above example, using JSPWiki, is attached to this issue
