Text is an important element in your PowerPoint slides, and most of the time, text alignment is taken care by the defaults set in your presentation template. You type or paste some text in a placeholder, and the text may align left, right, or even center, based upon the choices made in the template or Theme of the presentation. However, there are times when you want to make alignment choices, not just for text in placeholders, but also for text in text boxes, shapes, charts, tables, and anywhere else.
