The Facebook Shortcuts Cheat Sheet Saves You Time, Mouse Clicks
The chart is divided by OS (Windows and OSX) and browser (Chrome, Firefox, Safari, Internet Explorer). The list is really exhaustive and even includes some shortcuts that the Facebook power users among us weren't aware of.
Social Bakers notes: "If your computer does not contain a numerical keyboard (without numbers as the primary characters) and/or you don't have English set as your primary language, you will have to press 'Shift' with each of the keyboard shortcuts containing numbers."
