How to Set Tabs and Indents in PowerPoint 2013 Presentations
Grab the indentation doohickey and then drag it to change the indentation.
The indentation doohickey (that’s not its official name) is the control that looks like an hourglass sitting on a little box, normally positioned at the left side of the ruler.
It actually consists of three parts: the top upside-down triangle sets the indentation for the first line of the paragraph, the middle triangle sets the indentation for the remaining lines of the paragraph, and the box at the bottom sets the indentation for the paragraph. Try dragging the different parts of the indentation doohickey to see what happens.
