Today, reading online about PowerPoint, I read the following (the context is “positioning elements on a slide”):
there is a way to use x and y coordinates in PPT as you would in Quark or InDesign, but it’s not obvious so not everyone knows it.
OK, it’s not obvious. I don’t know it. Do you?
I don’t know how Quark and InDesign work, but one thing you could try in Powerpoint is to right-click on an object and select “Format <object type>” (e.g., if you right-click on a text box, the context menu item will read “Format Text Box”). In the “Format” dialog, there’s a “Position” tab.
