I will continue my thought a little more. I am fundamentally against using a mouse where you can perform an operation on the keyboard. It is clear that many operations can be performed only with the mouse, ... but there are operations that can and should be performed on the keyboard. If everything is done only with the mouse. this increases the operator's fatigue, as a result, the speed of work slows down and the number of input errors increases. ... One example of such work is the work of a cashier for accepting payments. We took measurements and definitely found out that working with the mouse is much slower and more tedious than the same work on the same program, but using only the keyboard keys. Therefore, there is a strict instruction for cashiers to use the mouse only when the operation cannot be performed using the keyboard.
Although theoretically everything can be done using the keyboard, but in this case it is assumed that one key (or one key combination) must be pressed on the keyboard.
