A method performed within a content editing device provides advanced editing functionality for use within application user interfaces having selectable content. The method provides automatic content insertion following a selection of an end location within the target document and selection of content for insertion at the selected end location. An editor moves content around within one or more documents by tagging the end location and selecting the content that is to be moved or copied to that end location. The method further enables efficient re-arrangement of multiple selected contents within a single document or across multiple application user interfaces by tagging each of the selected content with a sequence tag indicative of the relative content location within the re-arranged sequence of content. Once the content has been tagged, a selectable paste option automatically orders the various contents at the end location in correct sequence relative to each other.
