Which keyboard shortcut is used to decrease the bullet level in a list?

The keyboard shortcut that is used to decrease the bullet level in a list is Shift+Tab. This combination allows users to demote a bulleted or numbered list item to a higher-level bullet, effectively moving it back one indent level. When you use Shift+Tab, the selected list item shifts left, which is the visual representation of decreasing its level.

In the context of word processing applications, this is particularly useful for organizing content hierarchically. For example, if you have a detailed list with sub-items, pressing Shift+Tab will allow you to simplify the list structure by bringing items back to a previous tier. Understanding this shortcut enhances efficiency when formatting documents with nested lists, ensuring a more streamlined workflow.
