The next few Alt codes are focused on currencies, with a few Spanish-specific characters as well. This is helpful if one of your keyboard keys is non-operational.Īlt codes 32 through 126 are dedicated to these keys.

The first 31 alt codes are dedicated to fun characters like happy faces, arrows, and other common symbols: Alt Code SymbolĪlt 31 ▼ The Alt Codes for uppercase letters, lowercase letters, numbers, and keyboard symbolsĪs I mentioned earlier, you can use Alt codes to type characters you could otherwise type on your keyboard. The Alt codes for emoji and other fun characters OK – now let's break this list down by sections. These are inaccessible to people with visual disabilities, and make it hard for everyone to copy-paste the codes. It took me a while to assemble all of these get them looking good.Īs a developer, when I search for these codes I often get results that are image-based. (Note: this does not include the many, many characters from non-western European languages – otherwise it would be 100,000s of codes long.)īelow is a nice ASCII-formatted table of the most commonly-used symbols and characters. These Alt codes are also helpful if you have a keyboard with a stuck or missing key.īelow I will break down the entire list of alt keys by category. You can type a lot of characters that may not have a corresponding key on your keyboard – such as European language alphabetic characters, ASCII symbols, and even Chinese characters (also known as Hanzi, Kanji, or Hanja). As Greek letters are more often than not used as variables in mathematical formulas, a Greek letter appearing similar to the TeX rendering is more likely to be encountered in works involving mathematics.In Windows, you can type any character you want by holding down the ALT key, typing a sequence of numbers, then releasing the ALT key. This is in line with the convention that variables should be italicized.
The font used in the TeX rendering is an italic style. The table below shows a comparison of Greek letters rendered in TeX and HTML. The OpenType font format has the feature tag "mgrk" ("Mathematical Greek") to identify a glyph as representing a Greek letter to be used in mathematical (as opposed to Greek language) contexts. The Greek letter forms used in mathematics are often different from those used in Greek-language text: they are designed to be used in isolation, not connected to other letters, and some use variant forms which are not normally used in current Greek typography. In mathematical finance, the Greeks are the variables denoted by Greek letters used to describe the risk of certain investments. The Bayer designation naming scheme for stars typically uses the first Greek letter, α, for the brightest star in each constellation, and runs through the alphabet before switching to Latin letters. The archaic letter digamma (Ϝ/ϝ/ϛ) is sometimes used. Sometimes, font variants of Greek letters are used as distinct symbols in mathematics, in particular for ε/ϵ and π/ϖ. Small ι, ο and υ are also rarely used, since they closely resemble the Latin letters i, o and u. Those Greek letters which have the same form as Latin letters are rarely used: capital A, B, E, Z, H, I, K, M, N, O, P, T, Y, X. In these contexts, the capital letters and the small letters represent distinct and unrelated entities.
Greek letters are used in mathematics, science, engineering, and other areas where mathematical notation is used as symbols for constants, special functions, and also conventionally for variables representing certain quantities.
