Spell Check is available within Course/Site Content and across modules.
Spell Check will underline a misspelled word in red. Hold the Ctrl key on your keyboard and right-click the underlined word to view a list of suggested corrections.
If the spell-checker keeps underlining a word that is spelled correctly and that you often use, hold the Ctrl key on your keyboard, right-click the underlined word and select "Add to dictionary."
Your browser's spell checker must be installed/enabled in order to utilize the spell checker within SOLE.
