Final answer:
Kerning allows designers to adjust the space between two specific characters, ensuring a visually appealing text layout.

The precise space between two specific text characters can be adjusted using kerning. Kerning is the process of adjusting the distance between individual letterforms to achieve a visually pleasing result. In contrast, tracking affects the spacing uniformly over a range of characters, leading refers to the vertical space between lines of text, and alignment concerns the overall layout of the text block.
