2) Combination of keys:defaults write com.apple.Finder AppleShowAllFiles YES
Open a window in Finder, then press Command + Shift + . (dot).
It will show up hidden files.
To hide them again, you'll do the same thing but:

For the Combination of Keys, simply repress them.defaults write com.apple.Finder AppleShowAllFiles YES
Easy, right?
