Adjust line and paragraph spacing from the Text Properties panel. Tap on some text and the properties panel will slide in on the right. The Line spacing panel itself expands with a tap to reveal options for adjusting space both above and below a paragraph.
Line spacing is a paragraph attribute - it will affect the paragraph in which the text cursor is placed.
You can enter a fixed value (pts or px for example) for the line spacing - but it is usually better to enter a percentage value as this will cope better should you need to make changes to font size.
Use the space above and below paragraph as a more controlled alternative to the usual double return method for paragraph spacing.
