When you are entering text into a text box in PowerPoint, the text moves to the next line based on the right margin of the text box. There are times when you may want to move to the next line before the text reaches the right margin. Pressing the Enter key does not always work. If you are using bullets, it moves to a new bullet. If you have different spacing between paragraphs than between lines, it is going to look different.
The method to use to move to the next line is to hold down the SHIFT key and then press the Enter key.
This method will simply move to the next line within the same bullet or text box and continues the text as if the line had wrapped at the right margin.
