Latex Command, Declaration, Environment

Latex Commands / Latex Control Sequences

• A Latex command name starts with a backslash character ( \ ).
• LaTeX commands names are case sensitive so that \pagebreak differs from \Pagebreak 
• A command may be followed by zero, one, or more arguments. Required or Mandatory arguments are contained in curly braces, {...}. Optional arguments are contained in square brackets, [...].

Example:

 \centerline{This line will be centered}

Latex Declaration Form

Latex declaration form takes no arguments, as in {\itshape text}. Latex declaration include between curly brackets. The scope of the declaration form lasts until the next type style command or the end of the current group.

Example:

{\centering This line will be centered}

Latex Environment

The environment-name at the beginning must exactly match that at the end. This includes the case where environment-name ends in a star (*); both the \begin and \end texts must include the star.

Example:

\begin{center}

 This is line one. \\This is line two. \\This is line three.

\end{center}
