Type some text into the edit box. New text will be blue until the spelling and grammar check has been completed on it.
After text has been checked,
misspelled words will be displayed in red and words that were likely misused will be displayed in green.
Right-click on any word or space to see suggestions for that word or space. The numbers on the suggestion menu are the computed likelihood that each word is correct in the selected location,
compared to the other suggestions on the menu. If no number is given next to a suggestion, that suggestion could not be scored.
All proper names are considered equally likely in a given location, and are displayed on a separate submenu.
Setting the 'threshold' lower will cause more less-likely words to be highlighted.
