-The editing mode is determined by selecting the \texttt{arrow} or the \texttt{I-beam} in the Transport and Buttons bar.
-
-If the arrow is highlighted, it enables \emph{drag and drop mode}.
-In drag and drop mode, clicking in the timeline does not reposition the insertion point.
-Double-clicking in the timeline selects the entire edit the mouse pointer is over.
-Dragging in the timeline repositions the edit the mouse pointer is over.
-This is useful for reordering audio playlists, sorting movie scenes, or moving effects around.
-To cut and paste in drag and drop mode you need to set In/Out points to define an affected region.
-
-If the I-beam is highlighted it enables \emph{cut and paste mode}.
-In cut and paste mode, clicking (LMB) in the timeline repositions the \textit{Insertion Point}.
-Double-clicking in the timeline selects the entire edit the cursor is over (column).
-Dragging in the timeline highlights a region.
-The highlighted region becomes the region affected by cut and paste operations and the playback range during the next playback operation.
-Shift-clicking in the timeline extends the highlighted region.
-
-When highlighting a region, the start and end points are either aligned to frames or aligned to samples. When editing video, you will want to align to frames. When editing audio you will want to align to samples. Select your preference by using \texttt{Settings $\rightarrow$ align cursor on frames}.
+The editing mode is determined by selecting the \texttt{arrow}, or immediately to the right of the arrow,
+the \texttt{I-beam} in the Transport and Buttons bar. In figure~\ref{fig:insertion-points} you can see
+the green colored highlight on the arrow icon indicating that you are currently in
+\emph{drag and drop mode}.
+
+With the arrow highlighted for \emph{drag and drop mode}, a double click with the left mouse button in the timeline selects the edit the mouse pointer is over.
+Then dragging in the timeline repositions that edit and this can be used for moving effects,
+changing the order of playlists, or moving video pieces around.
+There are numerous methods to cut and paste in \emph{drag and drop mode} by setting In/Out points to define
+a selected region or using the Copy/Paste Behavior as outlined in \ref{sub:copy_paste_behavior}.
+In this mode, clicking the LMB in the timeline does not reposition the \textit{Insertion Point}.
+
+When the I-beam is highlighted, you are in \emph{cut and paste mode}.
+In cut and paste mode, clicking the LMB in the timeline does reposition the \textit{Insertion Point}.
+Double clicking in the timeline selects the entire edit the cursor is over, i.e. that column.
+Dragging in the timeline with the LMB pressed down, highlights a selected region and this is the region that is affected by cut
+and paste operations. It is also the playback range used for the subsequent playback operation.
+Holding down the Shift key while clicking in the timeline extends the highlighted region.
