Excel’s Ribbon is great for finding everything you might ever want to do in a spreadsheet, particularly things you don’t do frequently, like managing and querying data connections or automatically grabbing geographic statistics from the internet and inserting them into cells.
But if you’re looking to do things fast, you’ll find keyboard shortcuts far more useful. Why bother to lift your hands from the keyboard if you want to open or close a file, apply formatting to cells, navigate through workbooks, undo and redo actions, calculate all worksheets in all open workbooks, and more? With keyboard shortcuts you won’t have to.
There are keyboard shortcuts to accomplish a vast array of tasks in the Excel desktop client, in both the Windows and Mac versions. (Fewer shortcuts are available for the Mac, but you can create your own custom keyboard shortcuts if you like.)
