How to find the keymap for a given key sequence in a buffer
===========================================================
It would be good to put this list into the Active Keymaps node
in lispref/keymaps.texi.
I am glad you appreciate it. However there was a bit more to add. I got
some tips from Kim and made a new version. There is a question in this
about when the keymap entry is a keymap.

How to find the keymap for a given key sequence in a buffer
===========================================================
Go through the list below step by step. As soon as a hit is found in
any keymap (see KeyLookup) you normally are ready. However if the
keymap entry is a variable symbol or a string then you must restart
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???)
Note: When you finally find a function symbol through this process you
must also check for command remapping. This just replaces the
function symbol with another. It is not recursive.
*) First apply `extra-keyboard-modifiers' mask to each keyboard
character read.
*) Each character read from the keyboard may be translated according
to `keyboard-translate-table'.
*) Characters that are self-inserting are translated according to
`translation-table-for-input'. If a character is self-inserting then
you are ready.
*) Translate meta characters according to `meta-prefix-char' to a two
character sequence.
FIRST-MAP) Look in `special-event-map'.
*) If using `read-from-minibuffer' (directly or indirectly) then look
in the keymap given as parameter then look in this. Otherwise look
in `minibuffer-local-map'.
*) If using `read-no-blanks-input' to read from minibuffer then look
in `minibuffer-local-ns-map' first and then `minibuffer-local-map'.
*) If overriding-terminal-local-map look in this. Then go to GLOBAL.
*) If overriding-local-map look in this. Then go to GLOBAL.
*) Is there a "keymap" property of the text or overlay at point?
*) Look for minor mode keymaps in `emulation-mode-map-alists'.
*) Look for minor mode keymaps in `minor-mode-overriding-map-alist'
*) Look for minor mode keymaps in `minor-mode-map-alist'.
*) Is there a `local-map' property of the text or overlay at point?
*) Is there a "local keymap" (those are for major modes)?
GLOBAL) Look in the "current global keymap". (This is returned by
`current-global-map' and may be different from `global-map', see
`use-global-map'.)
*) If it is an ASCII function key sequences then look in
function-key-map. This map transforms to Emacs key sequences.
*) The possibly transformed sequence after applying `function-key-map'
is now handled to `key-translation-map' which works the same way.
*) If any transformation was made by `function-key-map' or
`key-translation-map' then take the new sequence and go back to
FIRST-MAP.
Note: You may also find the function `current-active-maps' useful.
