- By default, copying a MIDI region creates a <dfn>deep link</dfn>—both
- regions share the same data source, and edits to the contents of
- one will affect the other. To break this link, select
- <kbd class="menu">MIDI > Unlink from other copies</kbd> from the region
- context menu, after which the selected region(s) will have their own copies
- of <em>only</em> the data that they visually display on screen. You will not
- be able to trim the region back its original length after an Unlink operation,
- and the operation cannot be undone.
+ The vertical dimension of the region window is controlled by a
+ <dfn>scroomer</dfn> widget, which is a combination scroll/zoom tool for
+ altering the zoom level and range of visible MIDI data.
