I love doing Power Excel seminars. I was in Fort Wayne, doing a seminar at a baseball stadium, when a question popped up: If I double click on Sunday, it automatically fills down with Monday, Tuesday, Wednesday. Will your Ctrl key trick work to make it Copy? I don't want to have to use the pop-up menu to change back to Copy instead of Fill.
Why was this a great question? Because I had no idea that double-clicking a cell would cause the AutoFill to work!
In episode 1881, you will see how to AutoFill by Double Click, how to set up a custom list, a workaround to prevent the AutoFill and make it a copy, plus, in the outtake, a formula using INDEX ROW and MOD together.
