\paragraph{Split --- blade cut and hard edges:} You can cut the tracks into 2 pieces on the timeline by putting the hairline cursor on the place you want to do a cut and then using the character “x” or the scissors tool (figure~\ref{fig:cut}).

A \textit{cut} uses a non-empty selection region, where the \textit{blade cut} or \textit{split} has no duration in the selection, just a hairline. As usual the use of cut when a selection is set, deletes/cuts the highlighted area. In the case where an In point or an Out point exists on the timeline, the clip is split at the location of the In/Out point since it has priority over the cursor location. A blade cut simply splits the edit into two edits. In order to have the video and audio aligned, it works best to have Settings $\rightarrow$ Align cursor on frames. When a blade cut occurs, the edges are created as \textit{hard edges}. These are edges that cannot be deleted by track optimizations.
Cinelerra has built-in optimization on the timeline. So that whenever two parts on the timeline are sequential frames, it automatically optimizes by making them into 1 item. So if you are cutting, dragging, editing, or whatever and somehow frame \# 40 ends up right next to frame \# 41, it optimizes them together. This optimization affects many areas throughout the program code.
\paragraph{Cutting/Snapping edits} cuts from an edit handle to the insert point.
There are Edit Panel buttons which normally are used to move to the previous or next edit handle/label.

They look like tags and the letter E on the menu bar and are oriented forward/backward. These same buttons can be used to \textit{cut} from the insert pointer to the previous or next edit/label when the \texttt{ctrl+alt} keys are both pressed when the buttons are used. They \textit{snap} off the media instead of doing the standard re-positioning. This is useful to minimize the number of operations necessary to cut between edits/labels.
Instead of using the edit panel buttons, you can more easily use the following keyboard shortcuts to perform the same functions:
