Which key is used to show or hide the Standard toolbar

Ctrl + 7 is the keyboard shortcut used to show or hide the Standard toolbar in Excel. This shortcut toggles the visibility of the toolbar, allowing users to customize their workspace. However, it's worth noting that in modern Excel versions with the ribbon interface, this shortcut may have limited relevance as the ribbon has replaced traditional toolbars. The other options (Ctrl + F4, Ctrl + 3, Ctrl + 4) are not used for toolbar visibility.
