We all type words from time to time that spell check doesn’t recognize. Did you know that you can teach spell check words it doesn’t know? In many applications you can right-click on a word flagged as misspelled and add it to the spell check dictionary. Just place your cursor over the word, right-click, and select Learn Spelling. If you’ve taught the dictionary a new word, but would rather it un-learn it, you can right-click on the word in question and select Unlearn Spelling.
