You're tapping away at a forum post or email or somesuch in an application with no spellcheck. You want to use a word, but don't know how to spell it. Do you:

A) Use a different word that you do know how to spell.
B) Look up the word in an online dictionary.
C) Look up the word in a real world dictionary.
D) Open an program that does have spell check and type the word in there to check the spelling.
E) Never have this problem because you're such a good speller.
