Scrub Wheel

The Scrub Wheel tool is the round wheel at the right-hand end of the group of
editing tool buttons. Its function is similar to "rocking the reels" of a reel-to-reel
tape deck. Scrubbing allows playback at slow speed, even in reverse, to locate an
edit or punch-in point the old fashioned way - by ear. The Scrub function is
engaged by clicking on the Scrub Wheel button to highlight it. The S key
momentarily activates the Scrub tool, turning it off when you release the key.
When Scrub is engaged, clicking and dragging the mouse pointer horizontally
along the Marker Bar at the top of the track screen starts the transport playing on
all 24 tracks. Dragging it to the right plays forward, dragging it to the left plays
backward. The mouse acts as a throttle - the further you drag it, the faster the
transport plays, up to full speed. By using a side-to-side motion with the mouse
and listening to the playback, you can zero in on a point in the track that you're
trying to locate.
If you want to scrub just a single track, with the I-Beam and Scrub tools both
active, place the cursor on the track you want to hear, then click, and scrub.
Caution: Selecting the Scrub tool does not automatically deactivate the Hand
tool. If you scrub on a region with the hand tool active, you won't scrub, you'll
move the region.

Edit Clipboard

Cut, copy and paste editing operations are performed through the Clipboard. The
HDR24/96 clipboard follows the conventions common to word processors and
other computer-based editing tools. The editing clipboard buffer holds the result of
a single cut or copy operation (which could be performed on multiple items if
selected). The cut or copied section remains on the clipboard until replaced by the
next cut/copy operation.
For example, if two region Copy operations are performed successively, only the
second selection copied remains on the clipboard, with the first copied selection
going into the bit bucket to make room for the second. As long as a copy remains
on the clipboard, it may be pasted any number of times and to any location.
Each cut and paste operation is recorded on the History list. This possibly very
long edit list is retained only as long as the Project file is open.

History List Entries

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 of the Technical
Reference Guide. It's important to mention here
because the history that's listed, in addition to
recording passes, is that of all of your editing
operations. 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 and may 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
