I created a book that uses a lot of photo and page text associated with the pictures. I have decided that I need to increase the size of the font of the text. I have tried to go to individual pages, hi light the text in the text box and then change the font size. The program does not allow me to change the size. My would be to find some universal way to change the size all at once, and if there is one I would really like to know. But even if I have to change one text box at a time, it still will not allow me to do that. What is the secret here?
Edit > Select All Text Cells.
You need the book in grid view, and it does select all text cells, whether they are the photo captions or on the cover. You can use Ctrl (PC) or Cmd (Mac) click to deselect some of the cells, though it's fiddly.
