User interfaces for editing text in pen-based computing systems include: (a) a display portion that displays text; and (b) a correction interface that displays an editable text portion corresponding to at least a portion of the text. The correction interface accepts input via a stylus to enable changes to the editable text portion on a character-by-character basis (e.g., to add, delete, or change individual characters). The correction interface further may include or associate with a "suggestion list" portion that includes alternative(s) to substitute into the editable text portion and/or a "task list" portion that displays potential actions available through the interface. The invention also relates to systems, methods, and computer-readable media to activate, provide, and operate such interfaces.
