Ctrl + hotkeys
Keyboard shortcut (synonyms: hot key, shortcut (English shortcut), shortcut key, shortcut key, keyboard accelerator) (English keyboard shortcut, quick key, access key, hot key) (for software) - a kind of interaction interface with a computing device (computer, calculator), which is the pressing of a button / key (or key combination) on the keyboard, which is assigned (programmed) an action - commands (operations) executed by this system. As a rule, it partially duplicates the interface of a menu or buttons and serves to significantly speed up the work, as well as increasing the number of possible actions performed using the keyboard. Keyboard shortcuts are particularly widely used in real-time computer games, in which the speed of a player's reaction to developments is important - in particular, in strategies.
It's about the Ctrl or Control key. This key is most often located in duplicate on a standard keyboard, left and right, below the alphabetic keys.

Need to use
Using combinations allows you to assign several values to a single key, which significantly 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. With the usual press on this key, the entered number is squared. To perform "x³", a special modifier key is pressed beforehand to activate the secondary function (it may have names, for example, "shift", "2ndf", the inscription on it is usually blue, unlike the others, white), then the key is pressed "X²". This runs the command written at the top. Thus, one key is assigned two actions, which reduces the number of buttons on the calculator. You can add some more similar 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 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.
