You can expand or condense character spacing to create a special effect for a title, or re-align the position of characters to the bottom edge of the text-this is helpful for positioning the copyright or trademark symbols. Kerning works only with OpenType/TrueType or Adobe Type Manager fonts. You can use the Font dialog box to change the kerning setting for selected characters. Sometimes the space between two characters is larger than others, which makes the word look uneven.
Kerning is the amount of space between each individual character that you type.
