tracking
The spacing between {characters} in a line of {text}.
This is defined when a {font} is designed but can often be
altered in order to change the appearance of the text or for
special effects.
Tracking should not be confused with {kerning} which deals
with the spacing between certain pairs of characters.
See also {leading}.
