       keytest - tests the svgalib raw keyboard functions


       A  program  to test the low-level keyboard interface. This
       uses basic VGA functionality (or an svga  mode  you  spec-
       ify). Works only in 256 color modes.

       Cursor  keys  or keypad <1>, <2>, <3>, <4>, <5>, <6>, <7>,
       <8>, and <9> move  the  cursor.   Keypad  <0>  or  <Enter>
       changes  color.  <Q> or <Ctrl>-C quits. (autoquit after 60

       Note that the svgalib diagonal <7>, <9>, <1>, and <3> key-
       pad  keys emulation is flawed in that it emulates the ver-
       tical/horizontal keys. If one of  these  is  pressed  too,
       it's release confuses svgalib.

       The  top  pixel line shows a blue pixel for each key which
       is reported to be pressed.

       You can set a videomode to use by setting the  environment
       variable SVGALIB_DEFAULT_MODE to a number (see vgatest for
       a list) or a string like G0x1x2 where you replace  0  with
       desired x resolution, 1 with the desired y rez, and 2 with
       the desired number of colors (2, 16, 256, 32K,  64K,  16M,
       16M4).  Again,  only  certain  choices  are available, see
       vgatest for a list.

       In case nothing is selected, G320x200x256 is choosen.

       This demo is part of svgalib  and  can  be  found  in  the
       demos/  subdirectory of the original svgalib distribution.
       However, it is not installed in  the  system  by  default,
       s.t.  it  is unclear where you can find it if your svgalib
       was installed by some linux distribution. Even then,  when
       you  have the demo on your system, you probably won't have
       the sources s.t. it is only of limited use for you.

       In case of any such problem, simply get an svgalib distri-
       bution  from  the  net. You even don't need to install it.
       Just make in the demos/ subdirecty. As  of  this  writing,
       svgalib-1.2.12.tar.gz  is  the  latest  version and can be
       retrieved    by    ftp     from     at
       /pub/Linux/libs/graphics     and     at
       /pub/linux/sources/libs which will most probably  be  mir-
       rored by a site close to you.

       demo  as well as of the original documentation is unknown.

       It is very likely that both are at least  to  some  extent

       Occasionally  this  might  be  wrong. I hereby asked to be
