Using Office on a Windows touch tablet is difficult – because all the buttons and menu options are very close together. You end up choosing the wrong option by mistake. Frustrating! Solution has been given since the Office 2013 version was released. On top left corner of Office tools, look for the Touch Mode button.
Choose Touch Mode and miraculously your problem is solved – instantly. Of course, number of options available do not reduce (that is not an option for Microsoft!). But the SPACING between them increases so that you can confidently touch what you want with your finger.
Also notice that the right click menus, drop downs and galleries also get spaced out. Can you even begin to imagine how much extra effort went into implementing this feature? Appreciate it and use it!
