What key is used to increase the bullet level in Word?

In Microsoft Word, the Tab key is used to increase the bullet level in a list. When you create a bulleted list and want to create a sub-item or a nested bullet, pressing the Tab key indents the current bullet, effectively increasing its level in the hierarchy. This function is essential for organizing lists clearly, allowing users to create more structured and visually appealing documents.

In contrast, other keys serve different functions; for example, Ctrl and Shift are often used for commands related to text formatting or selection, while Enter is used to create new bullet points at the same level. Thus, using the Tab key effectively allows for the enhancement of list organization within Word documents.
