KEYBOARD COMMANDS

<strong>alsamixer</strong> recognizes the following keyboard  commands  to  control  the
       soundcard.

   <strong>General</strong> <strong>Controls</strong>
       The  <em>Left</em>  and  <em>right</em> <em>arrow</em>  keys  are  used to select the channel (or
       device, depending on your preferred terminology). You can  also  use  <em>n</em>
       (&quot;next&quot;) and <em>p</em> (&quot;previous&quot;).

       The  <em>Up</em>  and  <em>Down</em> <em>Arrows</em> control the volume for the currently selected
       device. You can also use <em>+</em> or <em>-</em> for the same purpose. Both the left and
       right signals are affected. For independent left and right control, see
       below.

       The <em>B</em> or <em>=</em> key adjusts the balance of volumes on left and  right  chan-
       using <em>Insert</em> (or <em>;</em>) and <em>Delete</em> (or <em>'</em>) respectively.

       <em>L</em> re-draws the screen.

   <strong>Quick</strong> <strong>Volume</strong> <strong>Changes</strong>
<em>PageUp</em> increases volume by 5.

       <em>PageDown</em> decreases volume by 5.

       <em>End</em> sets volume to 0.

       You can also control left &amp; right levels for the current channel  inde-
       pendently, as follows:

       [<em>Q</em> | <em>W</em> | <em>E</em> ]  -- turn UP [ left | both | right ]

       [<em>Z</em> | <em>X</em> | <em>C</em> ] -- turn DOWN [ left | both | right ]

       If  the  currently selected mixer channel is not a stereo channel, then
       all UP keys will work like <em>W</em>, and all DOWN keys will work like <em>X</em>.

   <strong>Exiting</strong>
       Quit the program with <em>ALT</em> <em>Q</em>, or by hitting <em>ESC</em>.  Please note  that  you
       might  need to hit <em>ESC</em> twice on some terminals since it's regarded as a
       prefix key.

BUGS

Some terminal emulators (e.g. <strong>nxterm</strong>) may not  work  quite  right  with
       ncurses,  but  that's their own damn fault. Plain old <strong>xterm</strong> seems to be
       fine.
