The system receives a user selection of text on the workspace page across a plurality of content blocks. The system updates the in-memory selection state to include a text selection range. The system receives a user edit to the selected text. The system identifies the plurality of content blocks within the text selection range. The system applies the user edit to the content blocks within the text selection range.
