Versions of the Lorem ipsum text have been used in typesetting at least since the 1960s, when it was popularized by advertisements for Letraset transfer sheets. [1] Lorem ipsum was introduced to the digital world in the mid-1980s, when Aldus employed it in graphic and word-processing templates for its desktop publishing program PageMaker .
The earliest editors (designed for teleprinter terminals) provided keyboard commands to delineate a contiguous region of text, then delete or move it. Since moving a region of text requires first removing it from its initial location and then inserting it into its new location, various schemes had to be invented to allow for this multi-step process to be specified by the user.
The Unicode Standard encodes almost all standard characters used in mathematics. [1] Unicode Technical Report #25 provides comprehensive information about the character repertoire, their properties, and guidelines for implementation. [1]
For most symbols, the entry name is the corresponding Unicode symbol. So, for searching the entry of a symbol, it suffices to type or copy the Unicode symbol into the search textbox. Similarly, when possible, the entry name of a symbol is also an anchor, which allows linking easily from another Wikipedia article. When an entry name contains ...
By contrast, a character entity reference refers to a sequence of one or more characters by the name of an entity which has the desired characters as its replacement text. The entity must either be predefined (built into the markup language), or otherwise explicitly declared in a Document Type Definition (DTD) (see [a]). The format is the same ...
In visual art, copying the works of the masters is a standard way that students learn to paint and sculpt. [1] Often, artists will use the term after to credit the original artist in the title of the copy (regardless of how similar the two works appear) such as in Vincent van Gogh's "First Steps (after Millet)" and Pablo Picasso's "Luncheon on the Grass, after Manet" (based on Manet's well ...
2 Control-D has been used to signal "end of file" for text typed in at the terminal on Unix / Linux systems. Windows, DOS, and older minicomputers used Control-Z for this purpose. 3 Control-G is an artifact of the days when teletypes were in use. Important messages could be signalled by striking the bell on the teletype.
The start of heading (SOH) character was to mark a non-data section of a data stream—the part of a stream containing addresses and other housekeeping data. The start of text character (STX) marked the end of the header, and the start of the textual part of a stream. The end of text character (ETX) marked the end of the data of a message.
