-\subsection{ND List Modification}
+\subsection{Modification}
 A ND list can be modified by reference with \cmdlink{nset}, and by value  with \cmdlink{nreplace}, using the same index argument syntax as \cmdlink{nget}. 
 If the blank string is used as a replacement value, it will remove values from the ND lists, as long as it is only removing along one dimension. 
 Otherwise, the replacement ND list must agree in dimension to the to the index argument dimensions, or be unity. 
 For example, you can replace a 4x3 portion of a matrix with 4x3, 4x1, 1x3, or 1x1 matrices.
 If modifying outside of the dimensions of the ND list, the ND list will be expanded to the new dimensions, like in the command \cmdlink{ndlist}.

+\section{N-Dimensional Mapping}
 The command \cmdlink{nmap} is a general purpose mapping function for N-dimensional lists in Tcl. 
 If multiple ND lists are provided for iteration, they must agree in dimension or be unity, like in \cmdlink{nset}. 
 Returns an ND list in similar fashion to the Tcl \textit{lmap} command.

+\subsection{Map Indices}
 The iteration indices of \cmdlink{nmap} are accessed with the commands \cmdlink{i}, \cmdlink{j}, \& \cmdlink{k}. 
 The commands \cmdlink{j} and \cmdlink{k} are simply shorthand for \cmdlink{i} with dimensions 1 and 2.
