- The <dfn>MIDI Tracer</dfn> is similar to the <a href="@@midi-list-editor">MIDI
- List Editor</a>, in the way that it displays MIDI information as a tabular text
- view, and has a vertical flow, i.e. the events follow a top to bottom time
- order.
+ The <dfn>MIDI Tracer</dfn> window, which is accessed by selecting <kbd
+ class="menu">Window > MIDI Tracer</kbd> from the main menu, is similar to
+ the <a href="@@midi-list-editor">MIDI List Editor</a> in that it displays
+ MIDI information as tabular text, and has a vertical flow (i.e. the
+ events follow a top to bottom time-oriented order).

- Its use is different though, as it is <em>not</em> bound to a specific region or track:
- the MIDI that is monitored is any global input or output Ardour presents to the
- system. It is hence a very useful option to monitor a MIDI port, be it an external
- controller/device or the in/output of any track.
