# What do you call the number sign on a telephone keypad?

The original design utilized a six-pointed symbol, although an asterisk (*) with five points is more usually seen in printing. [Citation required] The "#" key is formally known as the "number sign" key, although it is also known by various names such as "pound", "hash", "hex", "octothorpe", "gate", "lattice", and "square".

It was first introduced by AT&T in 1947 as part of a trial program using standard typewriter keys for remote dialing purposes. It has been widely used since then in telecommunications and information technology.

In computing, the number sign or hash mark (also called pound sign or hexadecimal character 0x20 or decimal 64) is used as a prefix to indicate the presence of a single digit in a computer word. It is commonly used in arithmetic expressions to represent 10: 1+1=2. The term "number sign" is also used informally to refer to any single-digit decimal number.

On telephones, the number sign plays a vital role in determining which key on the keyboard will be assigned to what number when calling a phone number. It is always the sixth key from the left on a standard American telephone keypad.

When calling someone up who has one of these phones, you would press the 6 key twice followed by the number you want to reach. If the person you are calling picks up, you have completed a successful call.

## What is the star button on a phone called?

The "*" symbol is also known as the "star key" or "asterisk key." Depending on one's nationality or personal taste, "#" is known as the "pound key," "hash key," "hex key," "octothorpe," "gate," or "square." (The Greek symbols alpha and omega were initially envisioned.) These can be used for a variety of purposes. For example, an asterisk can be used by a teacher to mark questions on an exam sheet or students' work.

The term "star button" refers to a physical button on modern phones that when pressed, produces a * character on the screen. This is different from the Star (*) Marker function which displays a highlighted box around certain words in a text message or email. The star button is still present on some older phones that do not have this feature, such as those made before 2007.

The star button is useful because it provides a quick way to mark things up in any app that supports marking up pages with special characters. For example, you could use it as a first step in editing a document: open the file in a word processing program like Microsoft Word or LibreOffice, click the star button once to add a marker, and then click it again to start typing a comment. When you're done, press the star button again to remove the marker.

## What is the numeric sign on the keyboard?

The octothorpe, often known as a hash, number sign, or pound sign, is the typographic mark "#" (two horizontal lines and two vertical lines, crossed). The # sign appears on the same key as the number 3 on US QWERTY keyboards. It may be written by holding Shift and tapping the 3 key at the same time. On some PC keyboards the # key is called "Clear".

It is used to indicate a number in text-based applications such as email, forums, and blogs. It is also used in place of decimal points in numbers that might otherwise cause confusion such as when currency amounts are discussed.

It is commonly believed that the octothorpe was created by Ralph Baer for the American Broadcasting Company's television show "Science Fiction Theatre", which ran from 1950 to 1955. However, this claim has been debunked by several sources including Wikipedia, which states that it is an English typographical symbol that began appearing in print around 1810.

The # sign is used as a placeholder in HTML documents. When a web page is displayed in a browser window, any text within ... tags is shown in blue text while any text within ... tags is shown in black text. This is useful when creating web pages with headings and paragraphs of different colors, as well as providing context about the surrounding content.

(sign/symbol) The "#" sign/symbol is sometimes known as the "pound sign" in America, but because this moniker is often confused with the name and symbol for British money (also known as the "pound"), most people throughout the world just refer to it as "hash." It is also known as the "number sign," but not in computer coding.

The "#" sign is used in many languages to represent a pound sign or number hash. In English it is usually called a "pound sign" and in other languages such as French and German, it is called a "nombre de guillemet" or "Geburtstagszahl". A "guillemet" is a small bracket [ ].

In computers, it is common to use the pound sign as a prefix meaning "to make zero copies of." So, for example, "zero-page" files are stored in memory locations that are marked with the pound sign so that these areas of memory are never written to hard disk.

Additionally, the pound sign is commonly used in shell scripts to identify lines that should be executed by itself; that is, without being included within another command. These special lines will be described in more detail below.

So, for example, a "pounder" is a program that performs some action.

## What are the symbols on the phone called?

The symbol on a telephone's "Pound" or "Number" Key (#) is also known as an Octothorpe. An Octothorpe is any of several characters, usually an eight-pointed star or other shape with a point in each direction, used to indicate a text-message digit in computer programming and related technologies.

The term "Octothorpe" comes from the words octo ("eight") and thorpe ("small field"). It was originally used to describe a special character used in programming languages to denote a pound sign (•#•).

It is based on the asterisk (*), which has long been used as a shorthand for multiplication. In fact, the asterisk was first used this way in 1823 by English mathematician William Rowan Hamilton.

Multiplication tables were already well-known at this time, but it wasn't until the 20th century that computers became able to multiply large numbers efficiently. In 1970, American computer scientist Donald E. Knuth introduced the use of asterisks as replacements for multipliers during his development of TeX, a typesetting program.

Since then, the octothorpe has found its way into many languages to represent multiplication.
