* Vietnamese uses the acute accent ( dấu sắc ), the grave accent ( dấu huyền ), the tilde ( dấu ngã ), the dot below ( dấu nặng ) and the hook above ( dấu hỏi ) on vowels as tone indicators.

This version also listed eight accents ( acute accent ( ´ ), grave accent ( ` ), circumflex ( ^ ), caron ( ˇ ), macron ( ¯ ), tilde ( ˜ ), trema ( ¨ ), and a superscript dot (˙) and nine punctuation marks (?

# < span id =" n-vi ">↑↑↑↑</ span > Vietnamese has five tone markers that can go on top ( or below ) any of the 12 vowels ( a, ă, â, e, ê, i, o, ô, ơ, u, ư, y ); e. g.: grave accent ( à, ằ, ầ, è, ề, ì, ò, ồ, ờ, ù, ừ, ỳ ), hook above ( ả, ẳ, ẩ, ẻ, ể, ỉ, ỏ, ổ, ở, ủ, ử, ỷ ), tilde ( ã, ẵ, ẫ, ẽ, ễ, ĩ, õ, ỗ, ỡ, ũ, ữ, ỹ ), acute accent ( á, ắ, ấ, é, ế, í, ó, ố, ớ, ú, ứ, ý ), and dot below ( ạ, ặ, ậ, ẹ, ệ, ị, ọ, ộ, ợ, ụ, ự, ỵ ).

This earliest question mark was a decoration of one of these dots, with the " lightning flash " perhaps meant to denote intonation ( or a tilde or titlo, named after the Latin word titulus, as in “ ·~ ”, like those wavy and more or less slanted marks used in lots of medieval texts for denoting various things such as abbreviations, and that would become later various diacritics or ligatures or modified letters used in the Latin script ), and perhaps associated with early musical notation like neumes.

Moreover, the horseshoe may replace ; the triple-bar may replace, and a tilde (~), Np, or Fpq, may replace ; ||, or Apq may replace ; and &, or Kpq, may replace, especially if these symbols are not available for technical reasons.

These combinations are designed to be easy to remember, as the circumflex accent ( e. g. â ) is similar to a caret (^), printed above the 6 key ; the diaeresis ( e. g. ö ) is similar to the double-quote (") above 2 on the UK keyboard ; the tilde (~) is printed on the same key as the #.

Most such changes are sporadic, but occasionally a sound law is involved, as Romance * tl > Spanish ld, thus * kapitlu, * titlu " chapter ( of a cathedral )", " tittle " > Spanish cabildo, tilde.

* in French, in Spanish and in Italian, accent marks and most other diacritical markings are ignored, except the tilde in Spanish: for instance, in French, the final E of answer ÊTRE can double as the final É of CONGÉ when written ETRE and CONGE ; but in Spanish, N and Ñ are distinct letters.

The tilde is used with many letters that are considered part of the alphabet.

In lexicography, the latter kind of tilde and the swung dash () are used in dictionaries to indicate the omission of the entry word .< ref >

In AmigaOS, dead keys are generated by pressing in combination with ( acute ), ( grave ), ( circumflex ), ( tilde ) or ( trema ) ( e. g., the combination followed by the key generates á and followed by generates é, whereas followed by generates à and followed by generates è ).

Nasal vowels are written a tilde or by a following ⟨ n ⟩ or ⟨ ŋ ⟩.

In other cases they are indicated through diacritics: Portuguese also marks nasality with a tilde, ã, õ, before other vowels ; Polish, Navajo, and Elfdalian use a hook underneath the letter, called an ogonek, as in ą, ę.

In the International Phonetic Alphabet, nasal vowels are denoted by a tilde over the symbol for the vowel, as in Portuguese.

Firstly, the extended Dynkin diagrams ( corresponding to tetrahedral, octahedral, and icosahedral symmetry ) have symmetry groups respectively, and the associated foldings are the diagrams ( note that in less careful writing, the extended ( tilde ) qualifier is often omitted ).

Different configurations can be purchased from Unicomp, including updated 104 / 105-key layouts, a " Linux " model ( where the Ctrl and Caps Lock keys, and the ESC and tilde keys, are swapped ), models with integrated Trackpoint pointing sticks or integrated trackballs, and POS-specific models, such as those with built-in magstripe readers.

* The graphics are still text-character based, but each character's foreground and background colors are independently assignable, and the character set could be edited to change the font, as well as to change unused characters such as the tilde or non-English characters into graphic symbols such as player pictures.

* C ++ has the naming convention in which destructors have the same name as the class of which they are associated with, but prefixed with a tilde (~).

It was emended in 1978 by Peter Wellnhofer into guinazui, because diacritical signs such as the tilde are not allowed in species names.

In some literature a subscript double tilde (≈) is sometimes used, as seen here on the letter ‹ a › ():

In the International Phonetic Alphabet, creaky voice of a phone is represented by a diacritical tilde for example.

Ñ ( lower case ñ, International Phonetic Alphabet: " énye ") is a letter of the modern Latin alphabet, formed by an N with a diacritical tilde.

The acute and the circumflex accent indicate stress and vowel height, the grave accent indicates crasis, the tilde represents nasalization, and the cedilla marks the result of a historical palatalization.

Sometimes the macron marks an omitted n or m, like the tilde:

) The tilde also marks nasality in the case of G ̃/ g ̃, used to represent the nasalized velar approximant by combining the velar approximant " G " with the nasalising tilde.

An older IPA subscript diacritic, called an ogonek, is still seen, especially when the vowel bears tone marks that would interfere with the superscript tilde.

The language, including the control structures and the expression grammar, was modeled on C. The C shell also introduced a large number of features for interactive work, including the history and editing mechanisms, aliases, directory stacks, tilde notation, cdpath, job control and path hashing.

Later a variant similar to the tilde (~) was also used.

S4C's logo was also refreshed in 1995, now using a dark red Futura typeface, and a tilde representing a dragon.

Filipino also is written with diacritics, but their use is very rare ( except the tilde ).

# < span id =" n-gn ">↑↑↑↑</ span > Guaraní also uses tilde over e, i, y, and g ( the last one not available precomposed in Unicode ), as well as digraphs ch, mb, nd, ng, nt, rr and the glottal stop '.

In later versions of NUTS 3 there was a harmless and quite useful little easter egg that would do a terminal video test just by printing NUTS 3 VIDEO TEST with many permutations of colour and other ANSI code character modifiers and the NUTS tilde control code that a user could use to activate it ( e. g.: ~ FR for Foreground Red ).

* Lithuanian uses the acute, grave and tilde in dictionaries to indicate stress types in the language's pitch accent system.

The tilde (, ; ˜ or ~ ) is a grapheme with several uses.

" This is expressed by saying that a proposition A is logically equivalent to not not-A ), or by the formula A ≡ ~(~ A ) where the sign ≡ expresses logical equivalence and the sign ~ expresses " not " or " negation ".< ref > Or alternate symbolism such as A ↔ ¬(¬ A ) or Kleene's * 49 < sup > o </ sup >: A ∾ ¬¬ A ( Kleene 1952: 119 ; in the original Kleene uses an elongated tilde ∾ for logical equivalence, approximaed here with a " lazy S ".

* Peace Corps Marshall Islands Marshallese Language Training Manual ( PDF, 275 KB ; instead of macrons uses trema on vowels and tilde on n, and underlines instead of cedillas )

In modern Microsoft Windows and Linux operating systems, the keyboard layouts US International and UK International feature dead keys that allow one to type Latin letters with the acute, grave, circumflex, diæresis, tilde, and cedilla found in Western European languages ( specifically, those combinations found in the ISO Latin-1 character set ) directly: "+ e gives ë, ~+ o gives õ, etc.

:* Estonian has a distinct letter õ, which contains a tilde.

: Some writers use the tilde (~), or N, instead of ; and some use the ampersand (&), the prefixed K, or instead of.

* tilde ( e. g. ã ) on a, n, o, A, N, O is generated by AltGr and #, then the letter ;

Alternatively, some use a tilde (~) or a wavy underline drawn beneath the symbol, which is a convention for indicating boldface type.

cases this is equivalent to entering the search term without tilde, but clicking on the " containing " option instead of going to the article.

The stripped name is then truncated to the first 6 letters of its basename, followed by a tilde, followed by a single digit, followed by a period "< tt >.</ tt >", followed by the first 3 characters of the extension.

# Beginning with Windows 2000, if at least 4 files or folders already exist with the same initial 6 characters in their short names, the stripped LFN is instead truncated to the first 2 letters of the basename ( or 1 if the basename has only 1 letter ), followed by 4 hexadecimal digits derived from an undocumented hash of the filename, followed by a tilde, followed by a single digit, followed by a period "< tt >.</ tt >", followed by the first 3 characters of the extension.
