-Mixer Window Controls
----------------------
+The _Mixer_ window, can be viewed by going to the main menu and clicking
+`Window > Mixer > Show Mixer`. Alternatively, you can press **Alt+M**.
 
-The second window, the **Mixer Window**, can be viewed by going to the
-main menu and clicking *Window > Mixer*.
+The main function of the _Mixer_ window is to display all the mixer strips for
+the various tracks and busses side by side for easy reference. This window is
+mainly used during the _mixing_ process. It also provides access to plugins and
+routing features. See the chapters on [understanding
+routing](en/recording-audio/understanding-routing/),
+[mixing](en/mixing-sessions/mixing-levels/), and [using
+plugins](en/mixing-sessions/using-plugins/) for details.

+signal usually travels through
+3. Optional _Monitor Section_ with features like _Pre/After Fade Listen_,
+_Exclusive Solo_ etc.
 
-This window also contains a listing of the available Mixer Strips in the
-upper left hand corner. The check boxes in this area can be used to view
-and hide the Mixer Strips of the different Tracks. Finally, there is an
-area for managing **Groups**.
