Super secret Excel shortcut - "copy visible"

If you do a lot of work in Excel, you may hide the columns you aren't working with or filter the data to see only certain information.

What happens if you copy something that spans that hidden data? The hidden data is copied (and pasted) too... UNLESS you first use

alt + ; 

and then do your copy. This will copy only the visible cells.
