Toolbar Adding a custom menu to Excel toolbar is very easy in Microsoft Excel 2010 and 2013. You will easily do this in a step by step format, by following me as I do it.
On the very top of the Microsoft Excel, you will see the tools. Click on the arrow pointing down.
Click on More Commands.
Note: Only follow this step, if the menu is not among the ones showing above more commands.
Click on the arrow beneath Choose Commander From (1), click on the menu you want in 2, and click add (3).
