<p>
  The Time Signature ruler allows changing the time signature within one
  session. In the example below, the session starts with a time signature of
  4/4, then switches to 3/4 at bar 5, then to 6/8 at bar 13. The division of the
  ruler and the bars/beats vertical lines on the canvas updates accordingly.

<p>
  Ardour also supports using complex time signatures such as 11/8 or 27/32.
</p>

<p>
  New time signature markers can be created in two ways:
</p>

<ul>
  <li><kbd class="mod1n"></kbd>-clicking on the ruler</li>
  <li>Right-clicking on the ruler, then selecting the
  	<kbd class="menu">New Time Signature</kbd> menu item</li>
</ul>

<p>
  In both cases a new window will open to specify time signature settings:
</p>

<p>
  The right-click menu for existing time signature markers provides two options:
</p>

<ul>
  <li><kbd class="menu">Edit…</kbd> to open the
  	<kbd class="menu">Edit Time Signature</kbd> dialog;</li>
  <li><kbd class="menu">Remove</kbd> to delete the selected time signature marker.</li>
</ul>
