Editing Typographical error (section)

==Marking typos==
===Typesetting===
Historically, the process of converting a [[manuscript]] to a printed document required a [[typesetter]] to copy the text and print a first "galley proof" (familiarly, "a proof"). It may contain typographical errors ("printer's errors"), as a result of human error during typesetting. Traditionally, a [[proofreader]] compares the manuscript with the corresponding typeset portion, and then marks any errors (sometimes called "line edits") using [[List of proofreader's marks|standard proofreaders' marks]].

===Typing===
[[File:Spelling Correction Example.jpg|thumb|right|[[Correction fluid]] was often used to correct typographical errors as (or after) the document was typed. The fluid was painted over the error and, when dry  the correct spelling was written on the new surface. Exceptionally, printing errors were painted out and a handwritten correction applied.]]
When using a [[typewriter]] without [[correction tape]], typos were commonly [[overstrike|struck out]] with another character such as a [[strikethrough]]. This saved the typist the trouble of retyping the entire page to eliminate the error, but as evidence of the typo remained, it was not aesthetically pleasing. [[Correction fluid]] was invented to hide the original mark and allow the typist to correct the error almost invisibly. [[Word processing]] software all but eliminated the need for this solution.

===Social media===
In computer forums, sometimes "^H" (a visual representation of the [[ASCII]] [[backspace]] character) was used to "[[epanorthosis|erase]]" intentional typos: "Be nice to this fool^H^H^H^Hgentleman, he's visiting from corporate HQ."<ref>[http://www.catb.org/~esr/jargon/html/writing-style.html Chapter 5.

In [[instant messaging]], users often send messages in haste and only afterward notice the typo. It is common practice to correct the typo by sending a subsequent message in which an [[asterisk]] (*) is placed before (or after) the correct word.<ref>{{cite book|last=Magnan|first=Sally Sieloff|url=https://books.google.com/books?id=dbYbGsgJclgC&q=asterisk&pg=PA260|title=Mediating discourse online|publisher=[[John Benjamins Publishing Company]]|year=2008|isbn=978-90-272-0519-3|series=AILA Applied Linguistics Series|page=260}}</ref>

===Textual analysis===
In formal prose, it is sometimes necessary to quote text containing typos or other doubtful words. In such cases, the author will write "[''[[sic]]'']" to indicate that an error was in the original quoted source rather than in the transcription.<ref>{{cite book|last=Wilson|first=Kenneth G.|url=http://www.bartleby.com/68/67/5467.html|title=The Columbia Guide to Standard American English.|publisher=[[Columbia University Press]]|year=1993|chapter=sic (adv.)|access-date=2007-11-12|archive-url=https://web.archive.org/web/20071211191251/http://www.bartleby.com/68/67/5467.html|archive-date=11 December 2007|url-status=dead}}</ref>
