Edit Toolbar

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

ToDo At some point I'll upload the backgroundless images from the theem directory. Also better with an image of the complete toolbar rather than separate pngs- James

I've made the backgroundless images. Do you want them as separate new images, or do you want to replace the existing images? All the backgroundless images I've made are 19 pixels high; most are 19 pixels wide except a couple that need to be a few pixels wider. Just to see what it would look like I've uploaded Tool_edit_cut_nobg.png and changed it on this page.
We need a new edit toolbar image with the link tracks button.
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

Editing

 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.

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.

 Silence: Replaces the currently selected audio with absolute silence.

Undo, Redo

 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.

Zooming

 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.

 Fit 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.
