Jeff AtwoodAdded a well deserved reward bounty to a Mac question -- I had no idea Macs DO NOT allow you to move word by word with keyboard shortcuts out of the box! https://apple.stackexchange.com/questions/52147/control-arrow-key-to-jump-to-the-next-word

@codinghorror I think default at least on modern OSes, option arrow moves word to word, control arrow does spaces, command arrow goes to start/end of line, shift arrow selects from where you are.
