+ "process of using filler text is sometimes called greeking, although the text itself may be nonsense, "
+ "or largely Latin, as in Lorem ipsum.\nASDF is the sequence of letters that appear on the first four "
+ "keys on the home row of a QWERTY or QWERTZ keyboard. They are often used as a sample or test case "
+ "or as random, meaningless nonsense. It is also a common learning tool for keyboard classes, since "
+ "all four keys are located on Home row.\nETAOIN SHRDLU is the approximate order of frequency of the "
+ "twelve most commonly used letters in the English language, best known as a nonsense phrase that "
+ "sometimes appeared in print in the days of \"hot type\" publishing due to a custom of Linotype "
+ "machine operators.\nLorem ipsum... is one of the most common filler texts, popular with "
+ "typesetters and graphic designers. \"Li Europan lingues...\" is another similar example.\n"
+ "Now is the time for all good men to come to the aid of the party\" is a phrase first proposed "
+ "as a typing drill by instructor Charles E. Weller; its use is recounted in his book The Early "
+ "History of the Typewriter, p. 21 (1918).[1] Frank E. McGurrin, an expert on the early Remington "
+ "typewriter, used it in demonstrating his touch typing abilities in January 1889.[2] It has "
+ "appeared in a number of typing books, often in the form \"Now is the time for all good men to "
+ "come to the aid of their country.\"\nThe quick brown fox jumps over the lazy dog - A coherent, "
+ "short phrase that uses every letter of the alphabet. See pangram for more examples.\nNew Petitions"
+ " and Building Code - Many B movies of the 1940s, 50s, and 60s utilized the \"spinning newspaper\" "
+ "effect to narrate important plot points that occurred offscreen. The effect necessitated the "
+ "appearance of a realistic front page, which consisted of a main headline relevant to the plot, "
+ "and several smaller headlines used as filler. A large number of these spinning newspapers "
+ "included stories titled \"New Petitions Against Tax\" and \"Building Code Under Fire.\" These "
+ "phrases have become running jokes among B movie fans, and particularly fans of Mystery "
+ "Science Theater 3000. \nCharacter Generator Protocol - The Character Generator Protocol "
