Undo
This will undo the last editing operation you performed to your project. You can undo as many times as you want, all the way back to when you opened the window. To undo many operations, select History... from the View Menu.
Redo
This will redo any editing operations that were just undone. After you perform a new editing operation, you can no longer redo the operations that were undone.
Cut
Removes the selected audio data and places it on the clipboard. Any audio to the right of the selection is shifted to the left. Only one "thing" can be on the clipboard at a time, but it may contain multiple tracks and clips.
Split Cut
Same as Cut, but none of the audio data to the right of the selection is shifted. This leaves a gap and also splits the existing audio clip into two clips that can be moved independently using the Move Tool.
Copy
Copies the selected audio data to the clipboard without removing it from the project.
Paste
Inserts whatever is on the clipboard at the position of the selection cursor in the project, replacing whatever audio data is currently selected, if any.
If the cursor is in the middle of an existing audio clip, the audio data to the right of the clip will be shifted over to accomodate the inserted audio. If the cursor is in a blank region between clips and there is enough room for the inserted audio, nothing will be shifted.
Trim
Deletes everything to the left and right of the selection.
Delete
Removes the audio data that is currently selected without copying it to the clipboard.
"silence"
Erases the audio data currently selected, replacing it with silence instead of removing it completely.
"split"
Moves the selected region into its own track or tracks, replacing the affected portion of the original track with silence. See the figure below:
"duplicate"
Makes a copy of all or part of a track or set of tracks into new tracks. See the figure below:
"selectall"
Selects all of the audio in all of the tracks.
"selectstarttocursor"
Selects all the audio from the start of the timeline to the current cursor.
"selectcursortoend"
Selects all the audio from the cursor to the end of project, which is as far as audio exists in the project.
"findzerocross"
Moves the cursor or the edges of the selection to the nearest point where the audio waveform passes though zero. Use this to help achieve click-free cuts in audio, as the two ends of the cut will exactly line up.
"cursororselectionsave"
Saves the current selection and position. This function only saves the selection boundaries, but not the actual audio data.
"cursororselectionrestore"
Restores the selection to the project. You need to have an existing selection for this to work.
"movecursor"
These commands provide quick and accurate ways to manoeuvre the cursor around the project to the start and end of tracks and selections.
"snapto"
Turns snapping of the cursor to a grid of time values on or off. When off, your cursor can be positioned on any sample in the audio file. When on, it is restricted to certain points in time, determined by the time format in use. This is useful if your project must follow an external timecode exactly.
