Excel has shortcut keys for practically everything but it’s hard to remember them all.
A few useful ones are: CTRL + 'copies the data from the cell above
CTRL + ; inserts today’s date (as a fixed value)
CTRL+SHIFT+$ formats the cell as currency CTRL+SHIFT+% formats the cell as a percentage
CTRL+SHIFT++ (CTRL and plus)inserts cells or rows (depending on what you have selected)
CTRL+- (CTRL and minus)deletes cells or rows (depending on what you have selected)
