Extend the selection to the last cell up

Windows shortcut 
CtrlShift
Mac shortcut 

If the active cell is empty, Excel will extend the selection to the first non-empty cell above the active cell. If the active cell is non-empty, Excel will extend the selection on the last non-empty cell above the active cell. On a Mac, the command key (⌘) can be used instead of the control key.

I work as a financial analyst and your page is a leading one I use to find so important info for daily tasks like formula explanation, how to construct different formulas and so on. This is brilliant! You helped me a lot. - Sarunas
