The Microsoft Word interface is optimized for your mouse by default. However, for users with touch-sensitive screens, it may be difficult to select commands with the more compact mouse mode. Enabling touch mode increases the size of your ribbon, buttons, and menu commands so you can better tap it with your finger.
Enabling Touch Mode
Only a few steps are required to activate Touch Mode. First, click on the little arrow to the right of the quick access bar.
This opens a menu where you can add and remove commands from the Quick Access Toolbar. It also includes the "Touch / Mouse Mode" option that you should now enable.
After adding this option to the Quick Access Toolbar, a new icon will appear allowing you to open a menu. You can switch between Mouse and Touch modes.
Continue and select the "Touch" option. You'll notice right away that the Ribbon and Quick Access bar are not only growing in size, but there's more space between each command.
