Have you ever noticed formatting like this in a text field?
The browser knows that 'Today' and 'Learned' are misspelled... but how?

true to enable the spellcheck magic. Right click each word for suggestions, dictionaries, etc. (Chrome).
Spellcheck is enabled by default on Chrome, but you will have to set it explicitly on some or all versions of Firefox and IE. Learn more here:
