<p>
The default <dfn>mono panner</dfn> distributes 1 input to 2 outputs. Its
behaviour is controlled by a single parameter, the <dfn>position</dfn>. By
default, the panner is centered.

<h2>Mono Panner User Interface</h2>

<img src="/images/mono-panner-annotated.png" alt="image of the mono panner"/>

<p class="note">
  The mono panner looks a quite similar to the
  <a href="@@stereo-panner">stereo panner</a>
  interface. The difference is that the L/R labels in the lower half
  of the mono panner do not move because there is no "width" to
  control.
</p>

<h2>Using the mouse</h2>

<p>To change the position smoothly, press the right button and drag
  anywhere within the panner. <em>Note: you do not need
  to grab the position indicator in order to drag</em>
</p>

<dl class="faq">

<dt>Reset to defaults</dt>

  of the panner</dd>

<h2>Keyboard bindings</h2>

<p>
When the pointer is within a mono panner user interface, the following
keybindings are available to operate on that panner:
</p>

<dl>
  <dt><kbd>&larr;</kbd> / <kbd class="mod1">&larr;</kbd></dt>
  <dd>move position 1&deg; / 5&deg; to the left</dd>
  <dt><kbd>&rarr;</kbd> / <kbd class="mod1">&rarr;</kbd></dt>
  <dd>move position 1&deg; / 5&deg; to the right</dd>
  <dt><kbd>0</kbd></dt>
  <dd>reset position to center</dd>
</dl>

<h2>Using the scroll wheel/touch scroll</h2>

<p>
When the pointer is within a mono panner user interface, the scroll
wheel may be used as follows:
</p>

<dl>
  <dt><kbd class="mouse">&uArr;</kbd> or <kbd class="mouse">&lArr;</kbd></dt>
  <dd>move position to the left by 1&deg;</dd>
  <dt><kbd class="mod1 mouse">&uArr;</kbd> or <kbd class="mod1 mouse">&lArr;</kbd></dt>
  <dd>move position to the left by 5&deg;</dd>
  <dt><kbd class="mouse">&dArr;</kbd> or <kbd class="mouse">&rArr;</kbd></dt>
  <dd>move position to the right by 1&deg;</dd>
  <dt><kbd class="mod1 mouse">&dArr;</kbd> or <kbd class="mod1 mouse">&rArr;</kbd></dt>
  <dd>move position to the right by 5&deg;</dd>
