In everyday word processing, typed text displays certain words underlined in red. These underlines mark terms outside the spell checker's dictionary.
Work continues smoothly across sessions. Text is entered, edited, and formatted as before. The familiar underlines appear on the same unfamiliar words, maintaining the expected interface behavior.
Upon returning to type or review the document, the underline vanishes from that word. It now appears as standard text, integrated without correction prompts.
The spell checker's dictionary has changed its treatment of the word. Recognition now includes what was previously excluded, evident only when the text is re-examined.
Document creation proceeds identically. The prior state of non-recognition is absent, replaced seamlessly in the editing flow.
