Answer 1

A return key, also known as an enter key, is a key on a computer keyboard typically found in the bottom right corner of the keyboard. When pressed, the return key is used to create a new line in a document or text box, and to execute a command or function such as submitting a form or sending a message. In word processing programs, the return key is used to move to the next line or start a new paragraph. In web browsers and email clients, the return key is often used to send a message or submit a search query.
