Don’t blow this off yet if you’re kinda’ sorta’ interested. These things aren’t documented by Microsoft, so it takes years to put these lists together … but then most of the commands stay the same version after version. So if you work in Office 2013 or 365 or whatever, this is probably still a good resource.
In Office, commands are all the buttons that you see on your ribbon(s), plus … all the optional commands you might like to use or add.
The table contains the name of each command, it’s location on the ribbon (or off of it), it’s VBA code, and some details about how to use the command.
† There’s an apocryphal story that 90% of the requests for new features for Office are things that are already included in those 2K commands.
