Described herein is a system and method for displaying annotation(s) of an electronic document. User input to review (e.g., scroll) the electronic document is received, until a selected portion of the electronic document is displayed within a viewport pane of a display. In response to the review input, annotation(s) (e.g., comment(s), comment thread(s), annotation thread(s)) anchored within the selected portion of the electronic document displayed within the viewport pane are identified. Which annotation of the annotation(s) to visually distinguish for a focus of the user is determined. The identified annotation(s) are displayed in an annotation pane, with the determined annotation visually distinguished (highlighted) for the focus of the user. In some embodiments, the anchor associated with the determined annotation is also visually distinguished to provide a contextual link to the user and/or hint(s) that provided a visual signal of annotation(s) associated with an anchor on a particular line are displayed.
