我需要将长目录放在面板中，但它超出了面板空间。我可以自定义目录的字体大小，使标题变小但都适合空间吗？或者，我可以使用两列面板吗？
一个玩具示例如下：
\documentclass[a4paper,11pt]{article}
\usepackage{hyperref}
\usepackage{comment}
\usepackage{truncate}
\usepackage{graphicx}
\usepackage{color}
\usepackage{colortbl}
\usepackage{calc}
\usepackage{amssymb}
\usepackage{amsbsy}
\usepackage{shortvrb}
\usepackage{fancybox}
\usepackage[screen,panelleft,gray,paneltoc]{pdfscreen}
\margins{.75in}{.75in}{.75in}{.75in}
\screensize{6.25in}{8in}
