The MapInfo Pro ribbon provides keytip support for users to navigate the tabs and commands without the use of a mouse. Keytips are a Windows ribbon convention for keyboard navigation. Keytips appear as small black indicators over the tabs and commands when you click the Alt key. You can progressively drill down levels within the ribbon by navigating the keystrokes as they appear on the user interface. To turn off keytipcs, press ESC.
For example, to access the Zoom-To Entire Layer on the MAP tab, press: Alt+M+ZT+L.
