# Edit Menu

### From Audacity Manual

The Edit menu provides the standard edit commands (Undo, Cut, Copy, Paste and Delete) plus many other commands specific to editing audio.

The Edit menu is divided into several sections.

Undo and Redo Remove Audio: Cut, Delete, Split Cut, Split Delete, Silence Audio, Trim Clip Boundaries: Split, Split New, Join, Detach at Silences Copy, Paste and Paste Text to New Label Duplicate Labeled Regions: Cut, Delete, Split Cut, Split Delete, Silence Audio, Copy, Split, Join, Detach at Silences | Select: All, None, Left at Playback Position, Right at Playback Position, Track Start to Cursor, Cursor to Track End, In All Tracks, In All Sync-Locked Tracks Find Zero Crossings Move Cursor: to Selection Start, to Selection End, to Track Start, to Track End Region Save and Region Restore Play Region: Lock, Unlock Preferences

## 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. The name of this menu item will change to reflect what will be undone; if you just recorded some audio, the menu item name will be Undo Record.

## 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.

## Remove Audio

### Cut

Removes the selected audio data and places it on the Audacity clipboard. Any audio to the right of the selection is shifted to the left. Only one item can be on the clipboard at a time, but it may contain multiple tracks and clips.

### Delete

Removes the audio data that is currently selected without copying it to the Audacity clipboard.

### 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 Time Shift Tool.

Can also be used to remove one or more adjacent labels without affecting any labels to right of the split cut. Select only in the label track over all the labels to be removed.

### Split Delete

Removes the selected audio without placing it on the Audacity clipboard, but does not shift the following audio. The preceding and following audio are now separate clips that can be moved independently.

Can also be used to remove one or more adjacent labels without affecting any labels to right of the split delete. Select only in the label track over all the labels to be removed.

### Silence Audio

Replaces the selected audio with silence. It does not remove labels in any label tracks included in the selection.

### Trim

Removes all audio from the current clip except the selected part, creating its own clip from the remaining audio. Does not affect or move other clips in the same track (note the audio in the clip to the right is unaffected).

## Clip Boundaries

### Split

Splits the current clip into up to three clips at the selection boundaries. The audio before, within, and after the selection can now all be shifted independently

### Split New

Does a Split Cut on the current selection in the current track, then creates a new track and pastes the selection into the new track.

### Join

If you select an area that overlaps one or more clips, they are all joined into one large clip. Regions in-between clips become silence.

### Detach at Silences

In a selection area that includes absolute silences, creates individual non-silent clips between the regions of silence. The silence becomes blank space between the clips.

## Copy

Copies the selected audio data to the Audacity clipboard without removing it from the project.

## Paste

Pastes audio which has been cut or copied to the Audacity clipboard, either inserting it into the selected track(s) at the cursor point, or replacing the current selection region(s).

The behavior of the paste command changes depending on the setting of "Editing clips can move other clips" in Tracks Preferences. If the option is checked pasting is always possible and following audio is shifted to make room. If this option is not checked there must be room for the pasted audio.

  Pasting inside a clip, with "Editing clips can move other clips" checked:

When you select Paste and the cursor is outside a clip, and there is enough room for the audio that is on the clipboard, the audio on the clipboard can be inserted without any other clips being shifted over if "Editing clips can move other clips" is not checked. If "Editing clips can move other clips" is checked, the following audio will always be moved.

  Pasting outside a clip, with "Editing clips can move other clips" checked:

  Pasting outside a clip, with "Editing clips can move other clips" not checked:

## Paste Text to New Label

Pastes the text on the system clipboard (or text from a label stored in the Audacity clipboard) at the cursor position in the currently selected label track. If there is no selection in the label track a point label is created. If a range is selected in the label track a range label is created.

The most recent text cut or copied to either clipboard is pasted. If you have copied or cut a label to the Audacity clipboard, the text of that label will be pasted. If you have cut or copied text to the system clipboard from an application other than Audacity, that text will be pasted.

If no label track is selected one is created, and a new label is created.

In the example below, the text "Question 1" was copied from a word processing document then the "Paste Text to New Label" command was executed.

## Duplicate

Creates a new track containing only the current selection as a new clip.

## Labeled Regions

A labeled region is a region in an audio track that is spanned by a label. The labeled region commands are available when a selection exists in a label track that spans one or more labels.

The Labeled Region commands apply the following commands to any labeled regions in the current selection area.

Cut, Split Cut, Copy
Delete, Split Delete, Silence Audio
Split, Join, Disjoin

  The selection shown above was created by dragging in the label track then shift-clicking in the audio track. Applying the Edit > Labeled Regions > Split Cut command results in this:
  Result: audio has been cut only in the region spanned by the label.

When Sync-Locked Tracks is on, the menu commands Labeled Regions > Cut and Labeled Regions > Delete are disabled.

## Select

The items in this cascading menu provide quick ways of selecting ranges of audio.

### All

Selects all of the audio in all of the tracks.

### None

Deselects all of the audio in all of the tracks.

### Left at Playback Position

When Audacity is playing or recording, sets the left boundary of a potential selection by moving the cursor to the current position of the green playback cursor (or red recording cursor). The selection can then be drawn by using "Right at Playback Position" (below).

### Right at Playback Position

When Audacity is playing or recording, sets the right boundary of the selection, thus drawing the selection from the cursor position to the current position of the green playback cursor (or red recording cursor). This is a quick way to mark a selection for future editing while playing or recording.

It will usually be more convenient while playing or recording to use keyboard shortcuts ( by default, [ and ] ) to set the left and right boundary respectively.

### Track Start to Cursor

Selects a region in the selected track(s) from the start of the track to the cursor position.

### Cursor to Track End

Selects a region in the selected track(s) from the cursor position to the end of the track.

### In All Tracks

Extends the current selection up and/or down into all tracks in the project.

### In All Sync-Locked Tracks

Extends the current selection up and/or down into all sync-locked tracks in the currently selected track group.

## Find Zero Crossings

Moves the edges of a selection region (or the cursor position) slightly so they are at a rising zero crossing point. This is a point where a line joining the audio samples rises from left to right and crosses the zero horizontal line. Cutting and pasting at a zero crossing helps avoid clicks by matching the height of the waveform at the join. Note: this feature does not necessarily find the nearest zero crossing to the current position. It aims to find the crossing where the average amplitude of samples in the vicinity is lowest.

## Move Cursor

The items in this cascading menu provide quick ways to move the cursor.

### To Selection Start

When there is a selection, moves the cursor to the start of the selection and removes the selection.

### To Selection End

When there is a selection, moves the cursor to the end of the selection and removes the selection.

### To Track Start

Moves the cursor to the start of the selected track.

### To Track End

Moves the cursor to the end of the selected track.

## Region Save

Saves the current selection region or cursor position as observed on the Timeline. Note this function does not save any actual audio data currently inside selection boundaries.

## Region Restore

Restores the selection region or cursor position to the project at its saved Timeline position. If a region is restored, this is only explicitly placed inside those tracks which are currently selected.

## Play Region

The items in this sub-menu allow you to lock and unlock the play region in the Timeline. See Play Regions in Playing and Recording.

## Preferences...

Displays the Preferences dialog.
