You have no choice: when working with tables, these are most commonly performed operations, and if you apply shortcuts, they will make you considerably more productive. Productivity is a consequence of faster work, as most tasks can be done exclusively using the keyboard. Especially when you use a laptop, because when you are on the go, you may not have the favorite programmer’s pet at hand.
