EDT MAPPER
You will be asked to press keys to create a custom mapping (under
X-Windows) of your keypad keys and function keys so that they can emulate
the LK-201 keypad and function keys or the subset of keys found on a
VT-100 series terminal keyboard. (The LK-201 keyboard is the standard
keyboard attached to VT-200 series terminals, and above.)
Sometimes, edt-mapper will ignore a key you press, and just continue to
prompt for the same key. This can happen when your window manager sucks
up the key and doesn't pass it on to emacs, or it could be an emacs bug.
Either way, there's nothing that edt-mapper can do about it. You must
press RETURN, to skip the current key and continue. Later, you and/or
your local X guru can try to figure out why the key is being ignored.
Start by pressing the RETURN key, and continue by pressing the keys
specified in the mini-buffer. If you want to entirely omit a key,
because your keyboard does not have a corresponding key, for example,
just press RETURN at the prompt.

ADDITIONAL FUNCTION KEYS
Your keyboard may have additional function keys which do not
correspond to any LK-201 keys. The EDT Emulation can be
configured to recognize those keys, since you may wish to add your
own key bindings to those keys.
For example, suppose your keyboard has a keycap marked \"Line Del\"
and you wish to add it to the list of keys which can be customized
by the EDT Emulation. First, assign a unique single-word name to
the key for use by the EDT Emulation, let's say \"linedel\", in this
example. Then, at the \"EDT Key Name:\" prompt, enter \"linedel\",
followed by a press of the RETURN key. Finally, when prompted,
press the \"Line Del\" key. You now will be able to bind functions
to \"linedel\" and \"Gold-linedel\" in edt-user.el in just the same way
you can customize bindings of the standard LK-201 keys.
When you have no additional function keys to specify, just press
RETURN at the \"EDT Key Name:\" prompt. (If you change your mind
AFTER you enter an EDT Key Name and before you press a key at the
\"Press\" prompt, you may omit the key by simply pressing RETURN at
the prompt.)
