<h2 id="selection_clocks">The Selection Clocks</h2>

<img src="/images/selection-clocks.png" alt="The range clocks">

<p>
  The current <dfn>selection range</dfn>, as set with the <a href="@@toolbox">Range Mode tool</a>,
  is displayed in these three clocks: start of the range, end of the range, and length.
</p>
<p>
  Clicking on the range clocks will locate to either the beginning or end of the punch range.
</p>
<p>
  <kbd class="mouse">Right</kbd> clicking on any of the clocks brings up a context menu
  allowing to change the type of time display between the <a href="@@editing-clocks">
  4 clock modes</a>, and to copy the selected clock's time to the clipboard.
</p>

<h2 id="punch_controls">The Punch Controls &amp; clocks</h2>

    The Punch Controls, and the related Punch clocks
  </figcaption>
</figure>

<p>
  The punch controls available in the main toolbar, work in conjunction with the
  punch clocks, only visible while in Editor Mode.
</p>

<p>
  The <kbd class="menu">In</kbd> and <kbd class="menu">Out</kbd> buttons relate
  to the Punch range, and allow to use only one of the two punch boundaries, or both:
</p>
<table class="dl">
  <tr><th>In only</th><td>Records from the In marker on, without a end boundary</td></tr>
  <tr><th>Out only</th><td>Records until the Out marker, without a beginning boundary</td></tr>
  <tr><th>In <em>and</em> Out</th><td>Records only between the In and Out markers</td></tr>
</table>

<p>
  The punch clocks can be controlled the same way as the range clocks (moving the playhead,
  and changing the display mode).
</p>

<h2 id="rec-mode">Recording mode</h2>

<p>
  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 &mdash;
  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
  &mdash; 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>.
  </td></tr>
