Most sections of this documentation are divided into two parts: an HTML page and the MTX file that created it. By comparing the source (MTX) files with the output (HTML) files you will quickly understand how to use the formatting elements being discussed.
In general, MTX is case insensitive. "%TITLE" and "%title" are equivalent for example. Letters used as part of embedded tags are a major exception. "{FtextF}" is not the same as "{ftextf}." The latter will cause an error since capital letters are required for these tags.
Since the curly brace characters ({}) are "reserved" as part of embedded tags, they do not normally appear in HTML pages created with MTX. For purposes of this documentation, special characters have been substituted for curly braces in the original MTX files. You will occasionally see odd characters when you view these files.
