As any user of this program knows, when making a presentation, text is set to automatically resize.  Often this is helpful but sometimes it’s tedious and one might find themselves wanting to turn this feature off on occasion.  To do so, simply right-click on the text box and uncheck auto-resize text.

(Note: yea this is stupid easy, but I’ve found myself looking it up several times.  Maybe if I blog it out I’ll remember next time.)
