What is the Insert key in the laptop

The Insert key on a laptop is a keyboard key that toggles between two text-editing modes: Insert mode and Overwrite mode.

1. Insert Mode (default): New text is inserted at the cursor position without replacing existing text.
2. Overwrite Mode: New text overwrites existing characters at the cursor position.

On most laptops, the Insert key might be shared with other keys, such as PrtSc or Fn, requiring the Fn key to activate it. Modern keyboards often omit it, but you can simulate its function in some applications by using shortcuts like Shift + 0 on the numeric keypad.
