What characters that display on the screen to not print indicating where the enter key the and the tab key were pressed?

When the Enter key is pressed, a line break is typically represented by a special character often referred to as a newline character (e.g., \n or LF for Line Feed). The Tab key insertion is usually represented by a tab character, often denoted as \t. These characters do not print visible symbols on the screen but instead affect the layout of text by creating space or moving the cursor to the next line or tab stop.
