MS Word Multiple Text Boxes formating with single command

[One2One]

Hello members. I have a document with lot of text boxes, more than 100. I have to change text font and size in all of the text boxes. Doing it one by one will take a long time. Is it possible to do by selecting all the text boxes at once and giving a single command. Any help would be highly appreciated. Many thanks. My email is easycontact@hotmail.com One2One
