For what purpose is the DELETE key used?

The DELETE key is primarily used to remove or delete lines of code within a programming context. When working in a code editor or an integrated development environment (IDE), pressing the DELETE key will remove the selected text or the character immediately to the right of the cursor, allowing developers to edit and refine their code efficiently. This functionality is essential for maintaining code clarity and correctness, as it helps in eliminating errors or unnecessary lines without the need for manual backspacing.

In programming environments, making rapid changes is often required, such as correcting syntax errors, removing outdated functions, or refining code structures, all of which are facilitated by the DELETE key. This capability is crucial for the iterative process of writing and debugging code, enabling programmers to adapt and improve their work quickly.
