I have attached my new version here. I realize there are more things
that should be converted from @code to @ref, but I need some help to
finish that.

@subsection Finding the keymap to use
The list below describes step by step how Emacs finds a keymap from a
given key sequence. As soon as a hit is found in any keymap (see
@ref{Key Lookup}) then if the keymap entry is a function the search is
over. However if the keymap entry is a variable symbol or a string
then Emacs restarts with the variable symbol value or the string from
FIRST-MAP.
The keymap entry could also be a keymap. In that case the next event
is looked up in that keymap. (But what happens if there is no hit
there, I can not find any documentation on this???)
@noindent
@emph{Note 1:} When Emacs finally find a function symbol through this
process it also checks for command remapping. This just replaces the
function symbol with another. It is not recursive.
@noindent
@emph{Note 2:} Characters that are bound to @code{self-insert-command}
are translated according to @code{translation-table-for-input} before
insertion.
@noindent
@emph{Note 3:} You may find the function @code{current-active-maps}
useful when looking into this.
@table @asis
@item START-HERE:
First apply @code{extra-keyboard-modifiers} mask to each keyboard
character read.
@end table
@itemize @bullet
@item
Each character read from the keyboard may be translated according to
@code{keyboard-translate-table}.
@item
Translate meta characters according to @code{meta-prefix-char} to a
two character sequence.
@example
For example, this normally maps M-x into ESC x.
@end example
@end itemize
@table @asis
@item FIRST-MAP:
Look in @code{special-event-map}.
@example
For example, this is where the @code{delete-frame} event is handled.
@end example
@end table
@itemize @bullet
@item
If using @code{read-from-minibuffer} (directly or indirectly) then
look in the keymap given as parameter then look in this. Otherwise
look in @code{minibuffer-local-map}.
@item
If using @code{read-no-blanks-input} to read from minibuffer then look
in @code{minibuffer-local-ns-map} first and then
@code{minibuffer-local-map}.
@item
If overriding-terminal-local-map look in this. Then go to GLOBAL.
@example
This is for example used by @code{Incremental Search}.
@end example
@item
If overriding-local-map look in this. Then go to GLOBAL.
@item
Is there a "keymap" property of the text or overlay at point?
@item
Look for minor mode keymaps in @code{emulation-mode-map-alists}.
@example
For example, this is used by @code{cua-mode} and @code{viper}.
@end example
@item
Look for minor mode keymaps in @code{minor-mode-overriding-map-alist}
@item
Look for minor mode keymaps in @code{minor-mode-map-alist}.
@item
Is there a @code{local-map} property of the text or overlay at point?
@item
Is there a "local keymap" (those are for major modes)?
@end itemize
@table @asis
@item GLOBAL:
Look in the "current global keymap". (This is returned by
@code{current-global-map} and may be different from @code{global-map},
see @code{use-global-map}.)
@end table
@itemize @bullet
@item
If it is an ASCII function key sequences then look in
@code{function-key-map}. This map transforms to Emacs key sequences.
@example
This is for example used when running Emacs on a VT-100 terminal.
@end example
@item
The possibly transformed sequence after applying
@code{function-key-map} is now handled to @code{key-translation-map}
which works the same way.
@item
If any transformation was made by @code{function-key-map} or
@code{key-translation-map} then take the new sequence and go back to
FIRST-MAP.
@end itemize
