+  The visible note range in a MIDI track can be controlled in two
+  principle ways: the note scroomer, or the scroll wheel of your
+  mouse.

+<h2 id="add-new-notes-using-the-mouse">Using the scroomer</h2>
+
+<p>
+  The scroomer offers two kinds of control. You can "grab" it in the
+  middle and move it up or down - this adjusts the absolute note range
+  displayed up or down. Alternatively you can "grab" the top or bottom
+  handle of the scroomer, and move that up or down - this adjusts the
+  extent of the note range displayed.

+
+
+<p>
+  Several scroll operations can be used to control the visible note
+  range:
+  <li>In internal edit mode, with no notes selected, unmodified
+    scrolling will move the visible range up and down.</li>
+  <li><kbd class="mod1">scroll</kbd> will increase and decrease the
+    visible range (zoom out and in)</li>
+  <li><kbd class="mod13">scroll</kbd> will expand either the top or
+    bottom of the visible note range (depending on scroll
+    direction). Think of this as "show me higher pitches" or "show me
+    lower pitches".
