KEYBOARD LAYOUT
Reading edition
There are two standard layouts in common use. The one most commonly used, especially in commercial shops, has the small capital layout shown on the keybuttons. The fractions run as side sorts when this layout is used. In the other standard layout the fractions are run in the keyboard. This is frequently used on newspapers for setting markets, stock reports, and tables, where a great number of fractions are used.
There are a variety of different keyboard layouts for different classes of work, but no great variation from the standard layout is advisable.
