+This last section on Dragging, outlines the difference
+between \textit{column selection} \index{column selection} and \textit{marking selection} \index{marking selection}.
+Column selection is available to make it easy to still be able to do
+some dragging in I-beam mode whereas Marking selection makes it easy
+to drag clips together that are not columnated.

+\subsection{Selection Methods}%
+\label{sub:selection_method}
+\index{edit!selection}
+\index{active region}
+
+Concerning \textit{Selection} methods, the following information is
+partially pertinent to all editing, but is most important to keep in
+mind when using Drag and Drop Editing.
+
+Originally, there was the column oriented timeline drag selection
+which can be seen in 1 of 3 ways:
+
+\begin{enumerate}
+\item a highlighted vertical column
+\item the colored line region between the [~in and out~] marker
+ labels
+\item a single flashing line
+\end{enumerate}
+
+The selection priority works like this. When the highlighted
+vertical drag column is in use (1), it has the highest precedence
+and is used as the selection. When the column is a single line (2),
+then the fall back selection is the [~in/out~] marker region, if
+they are set. When they are not set, and the cursor is flashing,
+then the selection start=end and the selection is empty, but it does
+have a position on the timeline which can be used for editing. This
+is input for the vertical style cut/paste drag/drop editing.
+
+More recently, in addition to the column oriented timeline drag
+selection, there is now \textit{group} \index{edit!grouping} capabilities which have
+various \textit{edit} selections. These are created in the Drag and
+Drop editing mode by clicking edits to toggle
+select/deselection. These groups are input to a different (more
+modern) set of cut, paste and overwrite drag/drop editing. You
+can see this set of operations when you click on an edit with the
+middle mouse button, and are also available using the shortcuts
+shown. They are more like text editor commands to include
+\texttt{ctrl+x=cut}, \texttt{ctrl+c=copy}, \texttt{ctrl+v=paste},
+and so on \dots The keyboard Delete key is not hooked to these
+operations, and is hooked to the original editing methods.
+
+In this \textit{group} mode, if there are In/Out \index{in/out point} markers set, they
+enter the selection priority queue between the column selection and
+the cursor only. You can see the In/Out markers selected region
+colored line across the timebar (slightly underneath where the time,
+samples or frames show ) on the main timeline extending between the
+[ and ]. This means that when the highlighted cursor selection is
+empty, the In/Out selection will be used.
+
+Summarizing: to select multiple edits/clips on the timeline you can simply use LMB on each edit. Or, if in \texttt{Settings $\rightarrow$ Preferences $\rightarrow$ appearence tab $\rightarrow$ Flags} we have enabled \textit{Clears before toggle}, use CTRL + LMB on each edit.
+
+There is also a faster way:
+
+\begin{enumerate}
+ \item Arm the tracks you want to be used.
+ \item Highlight the area as usually you do with \textit{I-beam} mode (or use \textit{In/Out Points}; or position \textit{Insert Point} over the stack of edits). If you miss an edit that you want included, the same method can be used to add it. It is an additive operation. And, it will include the partial edits in the selected area, thus making it easy to disinclude ones you do not want.
+ It will include silence also but you can remove that or any other edit with CTRL + LMB.
+ \item Press MMB on a clip inside the highlight area and the PopUp menu is shown with the \textit{Select edits} option on the top.
+ \item Choose the \textit{Select or Deselect edits} option and the clips inside the highlight area will be selected or deselected.
+\end{enumerate}
+
+And there is a Drag mouse way (this requires that the cursor be on the first
+clip and from there you start the drag):
+\begin{enumerate}
+ \item To Drag Select edits, hold down Alt+Left Mouse Button (LMB) and drag over the selection area. Releasing the mouse results in selecting.
+ \item To Drag Deselect edits. hold down Alt+Ctrl+LMB and drag over the area to be desected. Releasing the mouse results in deselecting.
+\end{enumerate}
+
+If using certain operating systems (for example Ubuntu and Arch) that might field the Alt key before it gets to \CGG{}, you can use the following for both Select and Deselect instead:
+\begin{enumerate}
+ \item Press and hold down Ctrl+Alt+LMB on an edit
+ \item Drag on the edits you want to select
+ \item Release the Ctrl key
+ \item Release the LMB
+ \item Release the Alt key
+\end{enumerate}
+
+\section{Inter-View Mode -- Identifying Source Targets}%
+\label{sec:inter-view_identifying_source_target}
+\index{inter-view}
+
+Inter-View mode provides a mapping of a particular media file to its
+timeline \index{timeline} usages. It is somewhat similar to Two Screen Editing in
+that you make use of the Viewer. It makes it possible to precisely
+trace and indicate in the media the origin of a particular segment
+of the timeline and visually indicate the use and distribution that
+the timeline makes of a particular media. A good example usage
+would be in the case of a 30 minute interview where you use a few
+short pieces to make a shorter 10 minute section, find out that you
+have made the timeline 12 minutes instead and need to cut out
+another 2 minutes. This feature provides the following capabilities:
+
+\begin{itemize}
+\item You can see on the timeline all of the places where a
+ particular piece of media was used.
+\item You can see which parts of that particular media are
+ already used so you do not reuse that same piece again.
+\end{itemize} Figure~\ref{fig:inter-view01} shows an example of the
+Inter-View mode mapping preview mini-window.
