Typewriters Used in Court
Stenotype Machines
Stenotype machines are used unanimously in all United States courts. They employ chorded keyboards, which look more like piano keys than typical typewriter keys. This specially designed keyboard allows stenographers to type rapidly using shorthand, a type of abbreviated symbolic writing. The full alphabet is missing from the keyboard, and full words do not instantly appear in the printed record. As a result, a stenographer has to later translate the record into plain English. Those unfamiliar with shorthand cannot read the initial transcription, as many words and phrases lack letters.
How They Work
Stenographers press multiple keys simultaneously to spell out entire words or common phrases. This process is referred to technically as "chording" or "stroking." When watching a stenographer use a stenograph machine, it appears as though she is playing a melody on a piano rather than typing.
Other typewriters
Although highly uncommon, a typewriter using a QWERTY keyboard, the modern keyboard most people are familiar with, may be used in courts. This type of typewriter is almost non-existent with court reporters, as they can type significantly faster with a stenotype machine. Some court clerks, however, may have a typewriter at their desk to fill out court documents and legal forms on demand. Most courthouses, however, primarily rely on modern computers.
