What is the purpose of the "Tab" key on the keyboard?

The "Tab" key serves a crucial function in text editing and formatting by allowing users to create indents or to jump to predefined tab stops within a document. When the "Tab" key is pressed, it moves the cursor forward to the next tab stop, enabling efficient alignment of text and organization of content. This is particularly useful in formatting lists, tables, and other structured documents where consistent spacing is necessary.

In contrast, other functions on the keyboard address different needs: deleting text involves the use of the "Delete" or "Backspace" keys, saving a document is typically executed with a combination of keys like "Ctrl + S," and switching applications is usually performed through shortcuts like "Alt + Tab." Therefore, the primary and distinguishing function of the "Tab" key is its unique ability to manage text alignment and formatting.
