However, if you need to dig in there, it’s easy to get to your user’s Library folder with a simple Go > Go to Folder command in Finder, then typing ~/Library.
Moapp also found a Terminal command that can bring your library folder back into focus.
Open the Terminal and type:
chflags nohidden /Users/[username]/Library/
Alternatively, reader PBenz pointed out that you can hold the Option key when clicking Finder’s Go menu to make a hidden Library option appear, as pictured.
And thanks to Paul Conigliaro, you can also assign a shortcut in System Preferences > Keyboard > Keyboard Shortcuts to open ~/Library. I used Command-Option-Shift-L.
