Results | Mark/UnMark Current Result

This menu item will mark the currently selected result (by clicking its checkbox). This menu item is a toggle, so if the current result is already marked, then it will be unmarked.

Marking a result means that it's relevant, and all other results, groups, and words will have their relevance bars updated based on the new marked result. The relevance bar is a measure of how related other results, groups, and words are to the marked result.
