  72   "Create an Emacs lisp file defining the TPU-edt keypad for X-windows.
  73
  74 This command displays an instruction screen showing the TPU-edt keypad
  75 and asks you to press the TPU-edt editing keys.  It uses the keys you
  76 press to create an Emacs Lisp file that will define a TPU-edt keypad
  77 for your X server.  You can even re-arrange the standard EDT keypad to
  78 suit your tastes (or to cope with those silly Sun and PC keypads).
  79
  80 Finally, you will be prompted for the name of the file to store the key
  81 definitions.  If you chose the default, TPU-edt will find it and load it
  82 automatically.  If you specify a different file name, you will need to
  83 set the variable ``tpu-xkeys-file'' before starting TPU-edt.  Here's how
  84 you might go about doing that in your init file.
  85
  86   (setq tpu-xkeys-file (expand-file-name \"~/.my-emacs-x-keys\"))
  87   (tpu-edt)
  88
  89 Known Problems:
  90
  91 Sometimes, tpu-mapper will ignore a key you press, and just continue to
  92 prompt for the same key.  This can happen when your window manager sucks
  93 up the key and doesn't pass it on to Emacs, or it could be an Emacs bug.
  94 Either way, there's nothing that tpu-mapper can do about it.  You must
  95 press RETURN, to skip the current key and continue.  Later, you and/or
  96 your local X guru can try to figure out why the key is being ignored."

 130     Start by pressing the RETURN key, and continue by pressing the keys
 131     specified in the mini-buffer.  You can re-arrange the TPU-edt keypad
 132     by pressing any key you want at any prompt.  If you want to entirely
 133     omit a key, just press RETURN at the prompt.
