User-Defined Macros

Abstract

LaTeX provides many in-built commands and environments for preparing a document. Besides those, it permits to define new commands and environments. Moreover, in-built ones can also be redefined to alter their behaviors. Many such cases are already addressed in previous Hours, which are systematically discussed in this Hour. In this book, although the original LaTeX syntax are printed in boldfaced sans serif fonts for their clear distinction, all user-defined syntax are printed in normal black color so that a reader is not misled.
