Answer 2

Answer:

backspace key

• Backspace ( ← 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, deletes the character at that position, and shifts back the text after that position by one position.
• The Backspace key or Back space key is a keyboard key that deletes any character before the cursor's current position. Note. The Backspace key is sometimes referred to as the rubout key. The rubout key was on early terminal and computer keyboards; it performed the same function as today's backspace key.
