I have iWork, but my teacher uses Microsoft Office. He makes these powerpoints that are like jeopardies for the class to compete with what we've learned. For the scores, he has these textboxes on one screen, and he can change the number while viewing it as a slideshow. However, when I download the powerpoint to Keynote, it's an uneditable textbox. Is there a option for me to add one in? Or would I have to use Microsoft Office for Mac? Oh, he also adds audio. Click a button, we get an answer wrong or right, etc. The buttons show, but I guess the audio has been removed.
