### LaTeX Commands

A LaTeX command begins with the command name, which consists of a \ followed by either (a) a string of letters or (b) a single non-letter. Arguments contained in square brackets [] are optional while arguments contained in braces {} are required.

Note: LaTeX is case sensitive. Enter all commands in lower case unless explicitly directed to do otherwise.

### LaTeX Environments

LaTeX environments are created by

    \begin{environment}  ...  \end{environment}


Declarations can be effected by an environment of the same name.
