To create a new keyboard shortcut, click the circular Office logo button at the top left of the main Word menu. Select Word Options from the bottom right of the displayed menu, then choose the Customize link in the navigation menu. In the “Customize the Quick Access Toolbar and keyboard shortcuts” menu, click Customize at the bottom of the left-side text next to the text “keyboard shortcuts.” Select the Category and the Command you want to make a keyboard shortcut, select the “Press new shortcut key” text-entry area and type the characters you want to make the shortcut. You’ll most likely have to replace an assigned shortcut. Then, press Assign and you’re done!
