MCQ Detailed View

The Ctrl key (short for Control key) is a modifier key found on all standard computer keyboards. Its main purpose is to work in combination with other keys to perform special commands or shortcuts. When you press the Ctrl key along with another key, it triggers a specific function that helps you work faster on a computer.

For example:

• 
  

  Ctrl + C = Copy selected text or items

  
  


• 
  

  Ctrl + V = Paste copied data

  
  


• 
  

  Ctrl + Z = Undo the last action

  
  


• 
  

  Ctrl + S = Save the current file

  
  

The Ctrl key does not do anything when pressed alone. It only functions when used with another key to issue a command. This helps improve productivity, especially in word processing, coding, data entry, and many other tasks.

Now let's briefly examine the incorrect options:

• 
  

  Typing capital letters is done using the Shift key, not Ctrl.

  
  


• 
  

  Moving the cursor is handled by arrow keys or a mouse.

  
  


• 
  

  Deleting text is done using the Delete or Backspace key.

  
  

So, the Ctrl key’s primary role is to execute shortcut commands in combination with other keys, making it an essential tool for efficient computer use.
