20 | /* Old BUGS: |
21 | - [M-C-a] != [?\M-\C-a] | |
22 | - [M-f2] != [?\e f2]. | |
23 | - (define-key map [menu-bar foo] <bla>) does not always place <bla> | |
24 | at the head of the menu (if `foo' was already bound earlier and | |
25 | then unbound, for example). | |
26 | TODO: | |
27 | - allow many more Meta -> ESC mappings (like Hyper -> C-e for Emacspeak) | |
28 | - Think about the various defaulting that's currently hard-coded in | |
29 | keyboard.c (uppercase->lowercase, char->charset, button-events, ...) | |
30 | and make it more generic. Maybe we should allow mappings of the | |
31 | form (PREDICATE . BINDING) as generalization of the default binding, | |
32 | tho probably a cleaner way to attack this is to allow functional | |
33 | keymaps (i.e. keymaps that are implemented as functions that implement | |
34 | a few different methods like `lookup', `map', ...). | |
35 | - Make [a] equivalent to [?a]. | |
36 | BEWARE: | |
37 | - map-keymap should work meaningfully even if entries are added/removed | |
38 | to the keymap while iterating through it: | |
39 | start - removed <= visited <= start + added | |

f63fd14e | 1099 | a symbol (when the key is looked up, the symbol will stand for its |
335c5470 | 1100 | function definition, which should at that time be one of the above, |
f63fd14e | 1101 | or another symbol whose function definition is used, etc.), |

1673 | Normally, `key-binding' ignores bindings for t, which act as default | |

1688 | If the optional argument POSITION is non-nil, it specifies a mouse | |

1690 | occurs in the keymaps associated with it instead of KEY. It can also | |
