Edit Toolbar

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

• Bill: Do we want to list the menu items and keyboard shortcut equivalents for the buttons.. snip .. I went ahead and did it. I really like how this looks now.
  
• JC: I like it too, and thanks to whoever uploaded the transparent-background images.

 Cut

Removes the selected audio data and places it on the clipboard. Equivalent to Edit > Cut and CTRL + X.

 Copy

Copies the selected audio data to the clipboard without removing it from the project. Equivalent to Edit > Copy and CTRL + C.

 Paste

Either inserts the clipboard contents at the position of the selection cursor, or replaces a selected area with the clipboard contents. Equivalent to Edit > Paste and CTRL + V.

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 tracks or tracks of indefinite length.

 Trim

Deletes everything but the selection. Equivalent to Edit > Trim and CTRL + T.

 Silence

Replaces the currently selected audio with absolute silence. Equivalent to Edit > Silence Audio and CTRL + L.

 Undo

Reverts the last editing operation. Equivalent to Edit > Undo and CTRL + Z. 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

Restores the previous editing operation that was just undone. Equivalent to Edit > Redo and CTRL + Y (on Mac SHIFT + CTRL + Z). 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.

 Link Tracks

This feature is not available in the 2.0 stable version. It is available in Audacity 1.3.9 beta.

Label tracks in Audacity can be linked to the audio tracks above them, and form a track group. You can turn this feature off by clicking this button to un-highlight it. See Label Tracks for more information. Equivalent to Tracks > Link Audio and Label Tracks

 Zoom In

Zooms in to a higher magnification level. Equivalent to View > Zoom In and CTRL + 1. You can continue to zoom in until you reach the level of displaying individual audio samples.

 Zoom Out

Zooms out to a lower magnification level. Equivalent to View > Zoom Out and CTRL + 3. You can zoom out so far as to fit 228 hours of audio on the screen.

 Zoom Selection

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. Equivalent to View > Zoom to Selection and CTRL + E.

 Fit Project

Zooms in or out so that the entire audio of the project fits in the available horizontal window area. Equivalent to View > Fit in Window and CTRL + F.
