Exceljet

Quick, clean, and to the point

Open options

Windows shortcut 
AltFT
Mac shortcut 
⌘,

This shortcut will open Excel's options area. We don't know of a dedicated shortcut for this in Windows, so you'll need to use Alt + F to open the File menu, then T to access the Options window.

On the Mac, options are called "preferences", and the shortcut command + , will open preferences in most applications, not just Excel.
