Right click in your home folder -> Show View Options -> Show Library Folder.

To get to it, you can also hold down Option when pressing the Go menu item.

I use a little shell script saved as an app created with automator for toggling hidden files:

showfiles=`defaults read com.apple.Finder AppleShowAllFiles` if [ "$showfiles" = "TRUE" ]; then defaults write com.apple.finder AppleShowAllFiles FALSE else defaults write com.apple.finder AppleShowAllFiles TRUE fi

In combination with the spotlight search it's really fast ;)
