# Edit Toolbar

### From Audacity Manual

These tools perform the same functions as those accessible through the Edit menu, View menu, Tracks menu and keyboard shortcuts.

  This image is not the default view. Only the Sync-Locking button is bold (active) until audio is present and selected in the project, the other buttons would be grayed-out on opening a new project.

## Cut Edit > Remove Audio or Labels > Cut or CTRL + X

Removes the selected audio data and/or labels and places these on the clipboard. By default, any audio or labels to right of the selection are shifted to the left.

## Copy Edit > Copy or CTRL + C

Copies the selected audio data and/or labels to the clipboard without removing these from the project.

## Paste Edit > Paste or CTRL + V

Either inserts the clipboard contents at the position of the selection cursor, or replaces a selected area with the clipboard contents.

The clipboard can only contain one item at a time, so cutting or copying to it always replaces any previous content. However that content may contain multiple audio tracks and/or label tracks of indefinite length, or multiple audio clips.

## Trim Audio Edit > Remove Audio or Labels > Trim Audio or CTRL + T

Deletes all audio but the selection. If there are other separate clips in the same track these are not removed or shifted unless trimming the entire length of a clip or clips. Does not affect label tracks.

## Silence Audio Edit > Remove Audio or Labels > Silence Audio or CTRL + L

Replaces the currently selected audio with absolute silence. Does not affect label tracks.

## Undo Edit > Undo and CTRL + Z

Reverts the last editing operation. Audacity supports unlimited "stepwise" undo. This means you can undo every editing operation back to the last time the project was opened, but you can't undo one particular edit without also undoing any changes made after that edit. You can review your editing history and jump straight back to any particular edit point at View > History....

## Redo Edit > Redo or CTRL + Y (on Mac SHIFT + CTRL + Z)

Restores the previous editing operation that was just undone. Note: If you undo an operation then perform any new one that appears in the Undo History, you can no longer redo that undone operation.

## Sync-Lock Tracks Tracks > Sync-Lock Tracks

The Sync-Lock Tracks feature ensures that length changes occurring anywhere in a defined group of tracks also take place in all audio or label tracks in that group, even if those tracks were not selected. This lets you keep existing audio or labels synchronized with each other, even when carrying out actions like inserting, deleting or changing speed or tempo. You can turn this feature "on" or "off" (default is "off") by clicking this button to highlight it. See Sync-Locked Track Groups for more information.

## Zoom In View > Zoom In or CTRL + 1

Zooms in to a higher magnification level. You can continue to zoom in until you reach the level of displaying individual audio samples.

## Zoom Out View > Zoom Out or CTRL + 3

Zooms out to a lower magnification level. You can zoom out so far as to fit 228 hours of audio on the screen.

## Zoom Selection View > Zoom to Selection or CTRL + E

Zooms a selection region in or out so that it fits in the available horizontal window area. The button is therefore grayed out unless a selection region is made.

## Fit Project View > Fit in Window or CTRL + F

Zooms in or out so that the entire audio of the project fits in the available horizontal window area.
