KEYBOARD COMMANDS
       alsamixer recognizes the following keyboard commands  to	 control  the
       soundcard.


   General Controls
       The  Left  and  right  arrow  keys  are used to select the channel (or
       device, depending on your preferred terminology). You can also  use  n
       ("next") and p ("previous").

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

       The B or = key adjusts the balance of volumes on left and right	chan-
       nels.

       M  toggles  muting  for the current channel (both left and right). You
       can mute left and right independently by using , (or <) and .  (or  >)
       respectively.

       SPACE  toggles recording: the current channel will be added or removed
       from the sources used for recording. This only works for	 valid	input
       channels,  of  course.  You can toggle left and right independently by
       using Insert (or ;) and Delete (or ') respectively.

       L re-draws the screen.


   Quick Volume Changes
       PageUp increases volume by 5.

       PageDown decreases volume by 5.

       End sets volume to 0.

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

       [Q | W | E ]  -- turn UP [ left | both | right ]

       [Z | X | C ] -- turn DOWN [ left | both | right ]

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


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

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