The combination of keys and the evolution of operating systems

The computer was originally created as an ideal assistant to the person and should facilitate the work connected with computing processes or with "digestion" of a large amount of information. Then, operating systems were invented (already to facilitate work with the computer). They were (and continue to represent) sets of various interrelated menus that performed the basic functions. This was a real breakthrough, because you no longer had to "drive" commands manually, it was enough to click a few times with the mouse, and all - the action is completed.

Despite the fact that this was a big step forward in the programming of operating systems, but with time and this seemed small - too much time was wasted searching for the desired item in the menu. For example, in order to copy or move a file from one place to another using the menu system, it was spent about a minute. And then the developers introduced a combination of "hot" keys, which replaced all these actions and allowed to reduce the time of this common operation 3 and more times. However, for this we had to slightly upgrade the keyboard: new keys were added - "Ctrl", and later - "Windows". The first suggested user combinations, the second - system actions (system and user shortcut mac os was achieved by using the "mac" button).

But the developers did not stop there, because in the near future some users found the standard combinations uncomfortable. Then in the operating systems was added the ability to assign their own keyboard shortcut to any action, which greatly facilitated and accelerated the work on the computer.

Now PC users all over the world use the most common combination of keys "ctrl + C" or "ctrl + V" every day and do not even think about the existence of other useful functions. And there are dozens of them in every operating system. Moreover, each separately installed program has its own combinations. Of course, remembering them all is not possible (and whether it is necessary, by and large?), But it is quite possible to pick up a couple of actions for yourself. To do this, go to the appropriate section of the help and carefully read the text.

Speaking of the main competitor of Windows as an operating system - the operating system Mac OS, you can not ignore the question of short combinations to facilitate the user's work. All of them are almost identical, but they have one significant nuance that depends on the keypad of these computers, which makes the work behind them not so convenient. It has only one control button and any combination of keys (mac + alphabetic or numeric key) can create some confusion in the work. However, users of this system probably already developed appropriate habits.

Finally it is worth mentioning about another feature of the Windows system. The system keys are located on the left and right sides of the keyboard. From this, it may be suggested that they are created for a trivial duplication, but in some cases the combination of the left keys may be different from the opposite ones.
