I was trying to make a matrix into a list and I found a great youttube video that showed me how to do it. but it used a shortcut I have never seen and I am having trouble finding more details on it. Alt+D +P opens a pivot table wizard that is different from the insert pivot table I am used to. i would like to know where this is from and any other details I can get on this. Is there a good resource for hidden shortcuts like this?
