Question

Which of the following key is used to delete a word or a line?
1. Alt
2. Shift
3. Insert
4. Backspace

Answer 1

Correct Answer - Option 4 : Backspace

The correct answer is Backspace.

• The backspace key is used to delete a word or a line.
• Backspace is the keyboard key that originally pushed the typewriter carriage one position backwards, and in modern computer systems moves the display cursor one position backwards.
• It deletes the character at that position, and shifts back the text after that position by one position.

• The Alt key on a computer keyboard is used to change (alternate) the function of other pressed keys.
• Thus, the Alt key is a modifier key, used in a similar fashion to the Shift key. 
• The shift key is a modifier key on a keyboard, used to type capital letters and another alternate "upper" characters. 
• The Insert key insert (often abbreviated Ins) is a key commonly found on computer keyboards.
