Edit Toolbar
Done - Bill
Do we want to list the menu items and keyboard shortcut equivalents for the buttons since we mention that in the intro? - Bill
Although having headers for each section of this toolbar was my idea, it isn't now consistent with the other toolbars where we agree we have a header per button (forced on us if there are no natural sections in the toolbar). Will play again with it later- Gale
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.
Paste
Either inserts the clipboard contents at the position of the selection cursor, or replaces a selected area with the clipboard contents.
Trim
Deletes everything but the selection.
Silence
Replaces the currently selected audio with absolute silence.
Undo
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
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.
Link Tracks
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.
Zoom In
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
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
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
Zooms in or out so that the entire audio of the project fits in the available horizontal window area.
