To move individual characters closer together or farther apart, adjust the kerning.
Select the text you want to adjust.
Choose Format > Font > Kern, and then choose an option from the submenu.
Tighten: Moves the characters together slightly.
Loosen: Moves the characters slightly apart.
Use Default: Tightens or loosens the distance between two characters if doing so makes them easier to read.
Use None: Disables the Use Default option.
You can choose Tighten or Loosen repeatedly to get the character spacing you want.
