How: To use these options, choose a Vertical Alignment option from the Text Box tab of the Measurements palette. 

The Inter ¶ Max field (available only when Justified is selected in the Type dropdown menu) lets you specify the amount of space that can be inserted between vertically justified paragraphs.
The Centered, Bottom, and Justified alignment options are intended only for rectangular text areas, and can be disrupted by obstructing items.

There are four options for positioning lines of text vertically within text boxes:

Top: In top-aligned text boxes, lines of text are positioned in the box with the top of the first line positioned as specified in the First Baseline area.
Centered: In center-aligned text boxes, lines of text are centered between the First Baseline’s ascent and the bottom of the text box.
Bottom: In bottom-aligned text boxes, lines of text are positioned with the last line flush with the bottom of the box.
Justified: In justified text boxes, lines of text are positioned in the box with the first line positioned as specified in the First Baseline area, the last line flush with text inset at the bottom of the box, and the remaining lines justified between.

When vertically justifying text, you can specify the maximum vertical distance between paragraphs.
