Keyboard Shortcuts Ctrl +
Keyboard shortcut (synonyms: hotkey, shortcut (shortcut), keyboard shortcut, keyboard accelerator) (keyboard shortcut, quick key, access key, hot key) (for software) - a kind of interaction interface with a computing device (computer, calculator), which is a press of a button / key (or combination of keys) on the keyboard that is assigned (programmed) some action - commands (operations) executed by this system. As a rule, it partially duplicates the interface of the menu or buttons and serves to significantly speed up the work, as well as to increase the number of possible actions performed using the keyboard. Keyboard shortcuts are especially widely used in real-time computer games, in which the player’s reaction to events is important - in particular, in strategies.

Need to use
Using combinations allows you to assign several values to one key, which significantly increases the number of actions performed from the keyboard. For example, in engineering calculators there is a “x²” key, over which, as a rule, “x³” is written. By pressing this key normally, the entered number is squared. To execute “x³”, a special modifier key is preliminarily 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 the key is pressed "X²". In this case, the command written above is executed. Thus, two actions are assigned to one key, which reduces the number of buttons on the calculator. You can add several more of these buttons to the calculator: “3rdf”, “4thf”, etc. After that, three, four or more commands can be assigned to one key.
On personal computers, Ctrl , Alt , Shift , and also 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.
