.SH KEYBOARD COMMANDS
\fBalsamixer\fP recognizes the following keyboard commands to control the soundcard. 

.SS
General Controls

The \fILeft\fP and \fIright arrow\fP keys are used to select the
channel (or device, depending on your preferred terminology). You can
also use \fIn\fP ("next") and \fIp\fP ("previous").

The \fIUp\fP and \fIDown Arrows\fP control the volume for the
currently selected device. You can also use \fI+\fP or \fI-\fP for the
same purpose. Both the left and right signals are affected. For
independent left and right control, see below.
 
The \fIB\fP or \fI=\fP key adjusts the balance of volumes on left and
right channels.

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

\fISPACE\fP 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 \fIInsert\fP (or \fI;\fP)
and \fIDelete\fP (or \fI'\fP) respectively.

\fIL\fP re-draws the screen.

.SS
Quick Volume Changes

\fIPageUp\fP increases volume by 5.

\fIPageDown\fP decreases volume by 5.

\fIEnd\fP sets volume to 0.

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

[\fIQ\fP | \fIW\fP | \fIE\fP ]  -- turn UP [ left | both | right ]

[\fIZ\fP | \fIX\fP | \fIC\fP ] -- turn DOWN [ left | both | right ]   

If the currently selected mixer channel is not a stereo channel, then
all UP keys will work like \fIW\fP, and all DOWN keys will work like \fIX\fP.

.SS
Exiting

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

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