+ The <kbd class="menu">Rec</kbd> button affects how the tracks behave when recording:
+</p>
+
+<table class="dl">
+ <tr><th>Non-Layered OFF <em>(default)</em></th>
+ <td>Tracks in <dfn>normal mode</dfn> will record non-destructively —
+ new data is written to new files, and when overdubbing, new regions will be
+ layered on top of existing ones. This is the recommended mode for most workflows.
+ </td></tr>
+ <tr><th>Non-Layered ON</th>
+ <td>Tracks using <dfn>non-layered mode</dfn> will record non-destructively
+ — new data is written to new files, but when overdubbing, the existing
+ regions are trimmed so that there are no overlaps. This does not affect
+ the previously recorded audio data, and trimmed regions can be expanded
+ again at will. Non-layered mode can be very useful for spoken word material,
+ especially in combination with <a href="@@pushpull-trimming">push/pull trimming</a>.
