I tend to use this option when I have some text that almost fits into a space but is over by one or two words. Rather than decrease the point size you can if you are careful squeeze the text a little so that it fits space but the type is no smaller. A word of warning though, don’t squeeze it too much because it will start to look ugly. From the style menu choose Horizontal/Vertical Shift. In the Scale box type in a value. I usually make it around 95 or 90%. Then click ok. What you have done is basically scale the text slightly to fit into the space.
