Need to use
The use of combinations allows you to assign several values to one key, which greatly increases the number of actions performed from the keyboard. For example, in engineering calculators there is an "x²" key, above which, as a rule, "x³" is written. When you press this key, the entered number is squared. To execute "x³", a special modifier key is pre-pressed to activate the secondary function (it can have names, for example, "shift", "2ndf", the inscription on it is usually blue, unlike others, white), then press the key "X²". The command written above is executed. Thus, one key is assigned two actions, which reduces the number of buttons on the calculator. You can add a few more buttons to the calculator: "3rdf", "4thf", etc. After that, you can assign three, four or more commands to one key.
On personal computers, Ctrl , Alt , Shift , and Windows ( Super ) or Command keys are most often used in combinations. They are often called modifier keys . In combinations, you can clamp not only one of these keys, but several at the same time.
