In the development process of computer programs and operating systems developers applied a huge number of innovations and improvements. Trying to improve the user experience and increase productivity, programmers invented the technology that allows you to specify a command not a single key of the keyboard, and combinations of several. Can be used any buttons in any quantity, but “gold standard” considered to be two to three keys. Combinations can be used for anything, such as on “Windows”: Alt + F4 produces the closure of the program window or open a menu, shutdown, Alt + Tab will switch between running applications, Ctrl + Alt + Del opens the “task”.

For various software products have their own combination of "hot keys", which is specially designed for maximum convenience of work in them. However, “hot” combinations of operating systems has priority over the software, if you do not have special conditions prescribed by the program.

A Little about the combinations of "hot keys»

For various operating systems and programs have their own particular use of keyboard shortcuts. So, on “Windows” the main commands start on Alt (for example Alt + F4 or Alt + Tab) in OS “Linux” commands start with Ctrl (e.g. Ctrl + Alt + F1 or Ctrl + Alt + D), in programs running under OS “Windows”, the control is performed also by Alt (the main command) and Ctrl (secondary). For the convenience of users, any program has the ability to customize their keyboard shortcuts. It is necessary to have administrator rights, go to the menu "program Settings" to select the sub-item "Purpose "hot keys", and combinations thereof" to appoint “Manually” and save the changes.

Any combination of keys can act right and back. For example, if Alt + F4 pressed once, the command will perform an assigned function. And pressing the combination again, you can undo the previous action. To describe all combinations of all software products is impossible and makes no sense, because different users need specific software. Consider in more detail the key combination Alt + F4 for OS “Windows”.

"Alt + F4" on your desktop

Since the emergence of the operating system “Windows” many users had at least once to use this button combination for their needs. For those who does not know and does not understand what it was about, the answer is: when you use the keyboard shortcuts on an active desktop window POPs up select an action:

  • Restart the computer;
  • Turn off computer;
  • Log off;
  • User selection.

‘Alt + F4" from the open window of the program

If the desktop is not active, and above it is running an application (film, game, Internet browser), then the specified key combination will simply close your application and frees memory.

Ctrl + X-cuts the file or text and puts it in the clipboard.
