To modify line spacing
Select the field or object
that you want to format.
In the
"Properties" view, go to the list of Text Format
properties, and set
Line Spacing
Type as
Multiple or
Exact.
Multiple refers to a multiple of the
font size you are using, while Exact refers an exact number of points.
Enter a number for the
Line
Spacing value.
If you chose Multiple, the number
you enter is multiplied by the font size of your text, and the program inserts
the result as line spacing. If you chose Exact, the number you enter is the
exact number of points that the program inserts for line spacing.
