PowerPoint enables you to use a technology called ink to draw freehand on your screen during a presentation. You use a pointer tool to do this. You can use ink to highlight or annotate an important point or to jot down ideas that come up during your interaction with the audience. You can choose the style and color used by the pen pointer.
