Two tiny features in PowerPoint that I learned fairly recently that I probably should have figured out years ago.
First, I often want to select a text field for purposes of moving it. I used to have to click in the field to select it, then click on the outside of the field to make it draggable, then drag it. Turns out you can hold down SHIFT while selecting a single text field and it gives the box the focus rather than the text inside.
Second, if you select a single object, then use one of the Align tools, it aligns the object to the slide. I’d always assumed you needed to select two objects in order to have something to align to. But selecting an object and then choosing Align to Center puts the object in the center of the slide.
