+% command to set the default table heading for button lists
+\newcommand{\btnhead}{\textbf{Key} & \textbf{Action} \\\midrule}
+
+% environment intended to be used with button maps
+% usage: \begin{btnmap}{caption}{label} Button & ButtonAction \\ \end{btnmap}
+% Note: this automatically sets the table lines.
+% Note: you *need* to terminate the last line with a linebreak \\
+% Note: you still need to enclose this with \begin{table} / \end{table}
+% Cheers for the usenet helping me building this up :)
