-The effect of each drag operation not only depends on the behavior button but whether the beginning or end of the edit is being dragged. When you release the mouse button, the trimming operation is performed.
-
-For all file formats, other than still images, the extent of the trimming operation is limited to the source file length. Attempting to drag the start of the edit beyond the start of the source, limits it to the source start. In all trimming operations, all edits which start on the same position as the cursor when the drag operation begins are affected. You have to disarm tracks in order to prevent edits from being affected.
-
-You have 6 different choices of which mouse button to use for specific types of editing while using the drag handle. You change the drag handle mouse effects by using the Settings $\rightarrow$ Preferences $\rightarrow$ Interface tab and modifying the Editing section as shown in the next figure~\ref{fig:trim}. The drag handle affects not only the clip you are working on but also frequently the entire duration of all clips on the timeline.\\

-A description of the fundamental/common terminology for choices follows.
-\begin{description}
- \item[All Edits (ripple)] shorten or lengthen the start or end of a single piece of media while moving all media to the right of that clip up or down on the timeline correspondingly. Timeline duration is modified. In a drag \textit{All Edits} operation, the beginning of the edit either cuts data from the edit if you move it forward or pastes new data from before the edit if you move it backward. The end of the edit pastes data into the edit if you move it forward or cuts data from the end of the edit if you move it backward. All the following edits shift. If you drag the end of the edit past the start of the edit, the edit is deleted.
- \item[One Edit (roll)] move the in and out point of a single clip without changing the timeline duration. In a drag \textit{One Edit} operation, nothing is cut or pasted. If you move the beginning or end of the edit forward, the source reference in the edit shifts forward. If you move the beginning or end of the edit backward, the source reference shifts backward. The edit remains in the same spot in the timeline but the source shifts.
- \item[Src Only (slip)] move the in and out point of a single clip without changing the timeline duration. In a drag \textit{Src Only} operation, nothing is cut or pasted. If you move the beginning or end of the edit forward, the source reference in the edit shifts forward. If you move the beginning or end of the edit backward, the source reference shifts backward. The edit remains in the same spot in the timeline but the source shifts.
- \item[Slide] a single clip is moved but retains its current in and out point; however the out point of the clip to the left changes and the in point of the clip to the right also changes. Timeline duration remains the same.
- \item[Edge Left / Right] moves the edge of the clips.
- \item[No effect] no changes are made. You might want to use this choice to prevent accidental movements.
