Which button moves the selected paragraph to the next lower heading level?

To move the selected paragraph to the next lower heading level in most Word processing software, you typically use the "Decrease Indent" button or a similar option in the formatting toolbar. This action often adjusts the paragraph style to a lower heading level. Additionally, keyboard shortcuts like "Shift + Tab" may also achieve this effect, depending on the software being used. Always check the specific application’s documentation for precise instructions.
