Spelling mistake found:
Dear Apple:
I would like to bring to your attention a spelling mistake in this lovely article.
Please see paragraph:
"Don't worry, you aren't permanently removing the item from your computer; you simply got rid of its Dock icon. If you want that item back in the Dock, ocate the application, file, or folder in the Finder (or with Spotlight), and drag it back into the Dock."
Incorrect: ocate
Correct: locate
Please update with correct spelling.
Thanks!
