بچه ها این گزینه در منوی format/font و در سر برگ chracter spacing قرار داره هر کاری کردم نفهمیدم کارش چیه شما می دونید این گزینه چی گار میکنه؟ 

kerning

n. (in
typography) technique of setting a pair of letters closer together than is
usual by reducing the space between them

Kerning for fonts   Automatically
adjusts the amount of space between certain combinations of characters so that
an entire word looks more evenly spaced. This command works for TrueType and Adobe
Type Manager fonts only. To use this feature, type or select the smallest font
size to which you want to apply kerning in the Points and above box.
Microsoft Word automatically kerns all fonts of that size and greater.
