<\body> Various standard markup is defined in . The following textual content tags all take one argument. Most can be found in the menu. <\explain|> Indicates an region of text. You can enter this tag via . <\explain|> Emphasizes a region of text like in ``the thing''. This tag corresponds to the menu entry \ . <\explain|> For definitions like ``a is a horny beast''.

This tag is obtained using . <\explain|> The name of a person like . This tag corresponds to . <\explain|> A bibliographic citation like a book or magazine. Example: Melville's . This tag, which is obtained using , should not be confused with . The latter tag is also used for citations, but where the argument refers to an entry in a database with bibliographic references. <\explain|> An abbreviation. Example: I work at the An abbreviation is created using or the keyboard shortcut. <\explain|> An acronym is an abbreviation formed from the first letter of each word in a name or a phrase, such as or .

You may enter verbatim text via . The tag may also be used as an environment for multi-paragraph text. <\explain|> Text which should be entered on a keyboard. Example: please type . This tag corresponds to the menu entry . <\explain|> Code of a computer program like in ``\ 1+1;> yields ''. This is entered using . For longer pieces of code, you should use the environment. <\explain|> Variables in a computer program like in >. This tag corresponds to the menu entry . <\explain|> This tag is used for mathematics inside regular text. Example: the formula x+cos x=1> is well-known. <\explain|> This is a tag which can be used inside mathematics for specifying that an operator should be considered on itself, without any arguments. Example: the operation > is a function from > to >. This tag may become depreciated. <\explain|> This is a physical tag for typewriter phase. It is used for compatibility with , but we do not recommend its use. Most of the following logical size tags can be found in (or ): <\explain> , , , , , , , , <|explain> These logical size tags should be used by preference when typesetting parts of your document in a larger or smaller font. Environments like footnotes or captions of tables may also be based on logical size tags. Document styles from professional publishers often assign very precise font settings to each of the logical size tags. By default, the size tags are rendered as follows: <\tm-fragment> The following are standard environments: <\explain|> Described above. <\explain|> Similar to , but for pieces of code of several lines. <\explain|> Environment for short (one paragraph) quotations. <\explain|> Environment for long (multi-paragraph) quotations. <\explain|> Environment for poetry. <\explain|> This is a physical tag for centering one or several lines of text.

The second argument can be made visible using . <\explain|> Unfolded presentation of a piece of content associated to a short title or abstract . The second argument can be made invisible using . <\explain|> Content which admits a finite number of alternative representation among which the user can switch using the function keys , , and . This may for instance be used in interactive presentations. The argument correspond to the currently visible presentation and to the set of alternatives. <\initial> <\collection>
