<P> The 21st century has seen a revival of interest in typewriters among certain subcultures, including makers, steampunks, hipsters, and street poets . </P> <P> According to the standards taught in secretarial schools in the mid-20th century, a business letter was supposed to have no mistakes and no visible corrections . Accuracy was prized as much as speed . Indeed, typing speeds, as scored in proficiency tests and typewriting speed competitions, included a deduction of ten words for every mistake . Corrections were, of course, necessary, and many methods were developed . </P> <P> In practice, several methods would often be combined . For example, if six extra copies of a letter were needed, the fluid - corrected original would be photocopied, but only for the two recipients getting "c.c." s; the other four copies, the less - important file copies that stayed in various departments at the office, would be cheaper, hand - erased, less - distinct bond paper copies or even "flimsies" of different colors (tissue papers interleaved with black carbon paper) that were all typed as a "carbon pack" at the same time as the original . </P> <P> In informal applications such as personal letters where low priority was placed on the appearance of the document, or conversely in highly formal applications in which it was important that any corrections be obvious, the backspace key could be used to back up over the error and then overstrike it with hyphens, slashes, Xs, or the like . </P>
