Edit operations may be undone or re-done in the order on which they appear on the History list.

History List

With the history list, editing isn't like heart surgery – the History list offers a safety net to undo any series of editing operations. The History List is discussed in detail in the List Panel section (page 21). It’s important to mention here because the history that’s listed, in addition to recording passes, includes all of your editing operations, and it’s the key to nondestructive editing. By deleting entries from the History list, you can undo any editing operation.

The following activities are recorded in the History List. They can be undone as long as the list remains active for the project: Record pass, split, crop, cut, copy, paste, move region(s), resize a fade-in, resize a fadeout, and resize a region. The only operation that isn’t recorded on the History list is Envelope modifications – node additions, movements or erasures.

Note: Backing up the edit list to or prior to a Record pass can be destructive. If you undo a Record pass, you’ll be asked if you want to delete the recorded audio. If you respond “YES”, the Record Pass will be removed from both the History List and the Region List. It’s history, and you can’t recover it, nor can you re-do any editing operations that followed the Record pass on the list. If you respond “NO” to the “Do you want to delete the recorded audio?” prompt, you’ll still move up the history list, but the list entries will remain intact – for the moment.

The next editing operation you perform while you’re above the Recording Pass entry in the History List will take precedence, and the Recording Pass entry, as well as the remainder of the History List, will disappear. The recorded audio remains in the Region List, however, so it can be recovered if necessary.

Cut

Cut removes the current selection (on one or multiple tracks) from the track area and places it on the clipboard. You can Cut either an area selection made with the I-Beam tool (on one or multiple tracks) or a region selected with the Hand tool. Cut works contiguously across empty track space in the selected area – i.e. unrecorded sections within the selected area are placed on the clipboard along with recorded audio in the selected area. If pasted elsewhere, the pasted section will include the blank spaces.

The Cut command is accessible from the pulldown Edit menu at the top of the GUI screen, or by clicking on the CUT button on the Tools panel. The keyboard shortcut is Ctrl-X.

Delete

The keyboard Delete key is similar to Cut, but not quite. It indeed cuts, but it does not place the cut segment on to the clipboard. After a Delete operation, the clipboard retains its previous contents. Delete operations are entered on the History List, so they can be undone.

Copy

The Copy command copies the selection(s) or selected region(s) from the track area to the clipboard. A region or selection is unaffected by a Copy operation. It remains where it was. Like Cut, Copy works contiguously across empty track space in the selected area – i.e. empty track space which is included in the area marked for copying is placed on the
