If you're trying to select an object in PowerPoint and you can't get it to be selected (maybe it's really small, maybe it's too close to another object, etc), you can use the keyboard to easily select the object. Just hit the Escape key once, then start hitting the Tab key. As you hit Tab, it will highlight objects in your PowerPoint document and it'll cycle through everything on the page. Just stop when your hard-to-select object is selected.
