This uses the same (very weak) string search as the current Find feature, but does it over the entire file. Matches are added to a table of results and displayed in the same dialog used by the References panel "copy out" feature. The reference table now jumps to a Location rather than just the closest offset, so that we can jump to the middle of a multi-line comment.
