 4.1 Sun Workstations Running X
 ==============================
 
 Some earlier Sun keyboards do not have arrow keys separate from the
 keypad keys.  It is difficult to emulate the full EDT keypad and still
 retain use of the arrow keys on such keyboards.
 
    The Sun Type 5 and other more recent Sun keyboards, however, do have
 separate arrow keys.  This makes them candidates for setting up a
 reasonable EDT keypad emulation.
 
    Depending upon the configuration of the version of X installed on
 your system, you may find the default X keynames for the keypad keys
 don’t permit Emacs to interpret some or all the keypad keys as something
 other than arrow keys, numeric keys, <Home>, <PageUp>, etc.  Both Sun
 and HP have been particularly guilty of making bizarre keysym
 assignments to the keypad keys.
 
    In most cases, the X Windows command, ‘xmodmap’, can be used to
 correct the problem.  Here’s a sample ‘.xmodmaprc’ file which corrects
 this problem on one Sun workstation configuration using an older SunOS
 release configured with a Sun Type 5 keyboard:
 
      ! File:  .xmodmaprc
      !
      ! Set up Sun Type 5 keypad for use with the Emacs EDT Emulation
      !
      keycode  53 = KP_Divide
      keycode  54 = KP_Multiply
      keycode  57 = KP_Decimal
      keycode  75 = KP_7
      keycode  76 = KP_8
      keycode  77 = KP_9
      keycode  78 = KP_Subtract
      keycode  97 = KP_Enter
      keycode  98 = KP_4
      keycode  99 = KP_5
      keycode 100 = KP_6
      keycode 101 = KP_0
      keycode 105 = F24
      keycode 119 = KP_1
      keycode 120 = KP_2
      keycode 121 = KP_3
      keycode 132 = KP_Add
 
    If ‘edt-mapper.el’ does not recognize your keypad keys as unique
 keys, use the command ‘xmodmap -pke’ to get a listing of the actual key
 codes and the keysyms mapped to them and then generate you own custom
 ‘.xmodmaprc’ similar to the one above.
 
    Next, feed ‘.xmodmaprc’ to the ‘xmodmap’ command and all the Sun Type
 5 keypad keys will now be configurable for the emulation of an LK-201
 keypad (less the <,> key).  In this example, the line
 
      keycode 105 = F24
 
 changes the X Windows name of the keypad <NumLock> key to be known
 internally as the <F24> key.  Doing so permits it to be configured to
 behave as the <PF1> (<GOLD>) key.
 
    The side effect of this change is that you will no longer have a
 <NumLock> key.  If you are using other software under X which requires a
 <NumLock> key, then examine your keyboard and look for one you don’t use
 and redefine it to be the <NumLock> key.  Basically, you need to clear
 the <NumLock> key from being assigned as a modifier, assign it to the
 key of your choice, and then add it back as a modifier.  (Unix
 for further help on how to do this.)
