Hi all

Short version:
How do I enable the function that dynamically alters the spacing between words and between letters, in order to get as close to uniform line lenght as possible?

Long version:
I'm trying to format a scipt for a book publication and have run into som trouble. The book format is A5, with lots of margin space and a generous font size. To conserve some space, and because I prefer the look of it, I would like the lines to have as close to uniform length as possible. To achieve that, I need a function that will increase the space between words and letters, to stretch the line as it were. I know it can be done in Word, but I can't for the life of me find out where to turn it on.

Any help dearly appreciated.
