The disadvantage is that it takes some digging (I still haven't seen all of them, often I stumble upon one I didn't know existed...) especially if you don't know the name of what you are looking for, but there are so many shortcuts, that any cheatsheet would either be incomplete or too long to be very practical (not to mention that shortcuts change sometimes; within the last two weeks one shortcut was added and changed!)
The Quick Favorites (shortcut Q) is also very handy. And many shortcuts can also be seen next to operations:
