I'm new to Keynote/PP, but not to desktop publishing. I'm trying to create a master slide with a placeholder text box, such that when text is input into the box in a slide, it flows downward like any regular text box in any other app on earth. That is, I want the top-left coordinate of the text box to stay the same, no matter how much text I put in. As it is, the text boxes seem anchored at their vertical midlines, so that large amounts of text cause the box to expand upwards, obscuring whatever is above it. I totally understand why this might be preferable in some situations, but not mine. Please advise... I'm going nuts here.
