To adjust the Kerning between individual letters, first make sure the text does not currently contain a Kerning adjustment. To do this, highlight the entire word, enter 0 in the Kerning adjustment box and click the cursor in the text box. Then place the cursor between the letters you want to apply the kerning adjustment to and enter a number. Click in the text box again to apply the new kerning adjustment. The following illustrates kerning adjusted to 200 between the C and the O. Leading Leading is the distance between lines of text.
Positive values add leading, while negative values reduce leading.
Leading applies to text that spans more than one line. When you create text in the text box and hit enter to create a new line of text, the default Leading is determined by the size of the font. If you have a fairly large font size, you probably won't want the large spacing between the lines of text, or if you have a small font, you might want to increase the space between the lines. To add space between lines of text, select the text and enter a positive number in the Leading box. To decrease the spacing, enter a negative number.
