| 42 /* A keymap contains six slots: | |
| 43 | |
| 44 parents Ordered list of keymaps to search after | |
| 45 this one if no match is found. | |
| 46 Keymaps can thus be arranged in a hierarchy. | |
| 47 | |
| 48 table A hash table, hashing keysyms to their bindings. | |
| 49 It will be one of the following: | |
| 50 | |
| 3025 | 51 -- a symbol, e.g. `home' |
| 428 | 52 -- a character, representing something printable |
| 53 (not ?\C-c meaning C-c, for instance) | |
| 54 -- an integer representing a modifier combination | |
| 55 | |
| 56 inverse_table A hash table, hashing bindings to the list of keysyms | |
| 57 in this keymap which are bound to them. This is to make | |
| 58 the Fwhere_is_internal() function be fast. It needs to be | |
| 59 fast because we want to be able to call it in realtime to | |
| 60 update the keyboard-equivalents on the pulldown menus. | |
| 61 Values of the table are either atoms (keysyms) | |
| 62 or a dotted list of keysyms. | |
| 63 | |
| 64 sub_maps_cache An alist; for each entry in this keymap whose binding is | |
| 65 a keymap (that is, Fkeymapp()) this alist associates that | |
| 66 keysym with that binding. This is used to optimize both | |
| 67 Fwhere_is_internal() and Faccessible_keymaps(). This slot | |
| 68 gets set to the symbol `t' every time a change is made to | |
| 69 this keymap, causing it to be recomputed when next needed. | |
| 70 | |
| 71 prompt See `set-keymap-prompt'. | |
| 72 | |
| 73 default_binding See `set-keymap-default-binding'. | |
| 74 | |
| 75 Sequences of keys are stored in the obvious way: if the sequence of keys | |
| 76 "abc" was bound to some command `foo', the hierarchy would look like | |
| 77 | |
| 78 keymap-1: associates "a" with keymap-2 | |
| 79 keymap-2: associates "b" with keymap-3 | |
| 80 keymap-3: associates "c" with foo | |
| 81 | |
| 82 However, bucky bits ("modifiers" to the X-minded) are represented in the | |
| 83 keymap hierarchy as well. (This lets us use EQable objects as hash keys.) | |
| 84 Each combination of modifiers (e.g. control-hyper) gets its own submap | |
| 85 off of the main map. The hash key for a modifier combination is | |
| 86 an integer, computed by MAKE_MODIFIER_HASH_KEY(). | |
| 87 | |
| 88 If the key `C-a' was bound to some command, the hierarchy would look like | |
| 89 | |
| 442 | 90 keymap-1: associates the integer XEMACS_MOD_CONTROL with keymap-2 |
| 428 | 91 keymap-2: associates "a" with the command |
| 92 | |
| 93 Similarly, if the key `C-H-a' was bound to some command, the hierarchy | |
| 94 would look like | |
| 95 | |
| 442 | 96 keymap-1: associates the integer (XEMACS_MOD_CONTROL | XEMACS_MOD_HYPER) |
| 428 | 97 with keymap-2 |
| 98 keymap-2: associates "a" with the command | |
| 99 | |
| 100 Note that a special exception is made for the meta modifier, in order | |
| 101 to deal with ESC/meta lossage. Any key combination containing the | |
| 102 meta modifier is first indexed off of the main map into the meta | |
| 442 | 103 submap (with hash key XEMACS_MOD_META) and then indexed off of the |
| 428 | 104 meta submap with the meta modifier removed from the key combination. |
| 105 For example, when associating a command with C-M-H-a, we'd have | |
| 106 | |
| 442 | 107 keymap-1: associates the integer XEMACS_MOD_META with keymap-2 |
| 108 keymap-2: associates the integer (XEMACS_MOD_CONTROL | XEMACS_MOD_HYPER) | |
| 428 | 109 with keymap-3 |
| 110 keymap-3: associates "a" with the command | |
| 111 | |
| 112 Note that keymap-2 might have normal bindings in it; these would be | |
| 113 for key combinations containing only the meta modifier, such as | |
| 114 M-y or meta-backspace. | |
| 115 | |
| 116 If the command that "a" was bound to in keymap-3 was itself a keymap, | |
| 117 then that would make the key "C-M-H-a" be a prefix character. | |
| 118 | |
| 119 Note that this new model of keymaps takes much of the magic away from | |
| 120 the Escape key: the value of the variable `esc-map' is no longer indexed | |
| 121 in the `global-map' under the ESC key. It's indexed under the integer | |
| 442 | 122 XEMACS_MOD_META. This is not user-visible, however; none of the "bucky" |
| 428 | 123 maps are. |
| 124 | |
| 125 There is a hack in Flookup_key() that makes (lookup-key global-map "\^[") | |
| 126 and (define-key some-random-map "\^[" my-esc-map) work as before, for | |
| 127 compatibility. | |
| 128 | |
| 129 Since keymaps are opaque, the only way to extract information from them | |
| 130 is with the functions lookup-key, key-binding, local-key-binding, and | |
| 131 global-key-binding, which work just as before, and the new function | |
| 440 | 132 map-keymap, which is roughly analogous to maphash. |
| 428 | 133 |
| 134 Note that map-keymap perpetuates the illusion that the "bucky" submaps | |
| 135 don't exist: if you map over a keymap with bucky submaps, it will also | |
| 136 map over those submaps. It does not, however, map over other random | |
| 137 submaps of the keymap, just the bucky ones. | |
| 138 | |
| 139 One implication of this is that when you map over `global-map', you will | |
| 140 also map over `esc-map'. It is merely for compatibility that the esc-map | |
| 141 is accessible at all; I think that's a bad thing, since it blurs the | |
| 142 distinction between ESC and "meta" even more. "M-x" is no more a two- | |
| 143 key sequence than "C-x" is. | |

| 1784 Define key sequence KEYS, in KEYMAP, as DEF. | |
| 1785 KEYMAP is a keymap object. | |
| 3086 | 1786 KEYS is the key sequence to bind, described below. |
| 428 | 1787 DEF is anything that can be a key's definition: |
| 1788 nil (means key is undefined in this keymap); | |
| 1789 a command (a Lisp function suitable for interactive calling); | |
| 1790 a string or key sequence vector (treated as a keyboard macro); | |
| 1791 a keymap (to define a prefix key); | |
| 1792 a symbol; when the key is looked up, the symbol will stand for its | |
| 1793 function definition, that should at that time be one of the above, | |
| 1794 or another symbol whose function definition is used, and so on. | |
| 1795 a cons (STRING . DEFN), meaning that DEFN is the definition | |
| 1796 (DEFN should be a valid definition in its own right); | |
| 1797 or a cons (KEYMAP . CHAR), meaning use definition of CHAR in map KEYMAP. | |
| 1798 | |
| 3086 | 1799 A `key sequence' is a vector of one or more keystrokes. |
| 1800 A `keystroke' is a list containing a key and zero or more modifiers. The | |
| 1801 key must be the last element of the list. | |
| 1802 A `key' is a symbol corresponding to a key on the keyboard, or to a mouse | |
| 1803 gesture. Mouse clicks are denoted by symbols prefixed with "button", | |
| 1804 followed by a digit for which button, and optionally "up". Thus `button1' | |
| 1805 means the down-stroke and `button1up' means the up-stroke when clicking | |
| 1806 mouse button 1. | |
| 1807 A `modifier' is a symbol naming a physical key which is only "noticed" by | |
| 1808 XEmacs when chorded with another key. The `shift' modifier is a special | |
| 1809 case. You cannot use `(meta shift a)' to mean `(meta A)', since for | |
| 1810 characters that have ASCII equivalents, the state of the shift key is | |
| 1811 implicit in the keysym (a vs. A). You also cannot say `(shift =)' to mean | |
| 1812 `+', as that correspondence varies from keyboard to keyboard. The shift | |
| 1813 modifier can only be applied to keys that do not have a second keysym on the | |
| 1814 same key, such as `backspace' and `tab'. A mouse click may be combined with | |
| 1815 modifiers to create a compound "keystroke". | |
| 1816 | |
| 1817 The keys, mouse gestures, and modifiers that are available depend on your | |
| 1818 console and its driver. At a minimum the ASCII graphic characters will be | |
| 1819 available as keys, and shift, control, and meta as modifiers. | |
| 1820 | |
| 1821 To find out programmatically what a key is bound to, use `key-binding' to | |
| 1822 check all applicable keymaps, or `lookup-key' to check a specific keymap. | |
| 1823 The documentation for `key-binding' also contains a description of which | |
| 1824 keymaps are applicable in various situations. `where-is-internal' does | |
| 1825 the opposite of `key-binding', i.e. searches keymaps for the keys that | |
| 1826 map to a particular binding. | |
| 1827 | |
| 1828 If you are confused about why a particular key sequence is generating a | |
| 1829 particular binding, and looking through the keymaps doesn't help, setting | |
| 1830 the variable `debug-emacs-events' may help. If not, try checking | |
| 1831 what's in `function-key-map' and `key-translation-map'. | |
| 1832 | |
| 1833 When running under a window system, typically the repertoire of keys is | |
| 1834 vastly expanded. XEmacs does its best to use the names defined on each | |
| 1835 platform. Also, when running under a window system, XEmacs can tell the | |
| 1836 difference between the keystrokes control-h, control-shift-h, and backspace. | |
| 1837 If the symbols differ, you can bind different actions to each. For mouse | |
| 1838 clicks, different commands may be bound to the up and down strokes, though | |
| 1839 that is probably not what you want, so be careful. | |
| 1840 | |
| 1841 Variant representations: | |
| 1842 | |
| 1843 Besides the canonical representation as a vector of lists of symbols, | |
| 1844 `define-key' also accepts a number of abbreviations, aliases, and variants | |
| 1845 for convenience, compatibility, and internal use. | |

| 3086 | 1853 A keystroke may be represented by a key; this is treated as though it were a |
| 1854 list containing that key as the only element. A keystroke may also be | |
| 1855 represented by an event object, as returned by the `next-command-event' and | |
| 1856 `read-key-sequence' functions. A key sequence may be represented by a | |
| 1857 single keystroke; this is treated as a vector containing that keystroke as | |
| 1858 its only element. | |
| 1859 | |
| 1860 A key may be represented by a character or its equivalent integer code, | |
| 1861 if and only if it is equivalent to a character with a code in the range | |
| 1862 32 - 255. | |
| 1863 | |
| 1864 For backward compatibility, a key sequence may also be represented by a | |
| 1865 string. In this case, it represents the key sequence(s) that would | |
| 1866 produce that sequence of ASCII characters in a purely ASCII world. An | |
| 1867 alternative string representation is keyboard macro notation, which can | |
| 1868 be translated to the canonical representation with `kbd'. | |
| 1869 | |
| 1870 Examples: | |
| 1871 | |
| 1872 The key sequence `A' (which invokes `self-insert-command') is represented | |
| 1873 by all of these forms: | |
| 428 | 1874 A ?A 65 (A) (?A) (65) |
| 1875 [A] [?A] [65] [(A)] [(?A)] [(65)] | |
| 1876 | |
| 3086 | 1877 The key sequence `control-a' is represented by these forms: |
| 428 | 1878 (control A) (control ?A) (control 65) |
| 1879 [(control A)] [(control ?A)] [(control 65)] | |
| 3086 | 1880 |
| 1881 The key sequence `control-c control-a' is represented by these forms: | |
| 428 | 1882 [(control c) (control a)] [(control ?c) (control ?a)] |
| 1883 [(control 99) (control 65)] etc. | |
| 1884 | |
| 3086 | 1885 The keystroke `control-b' *may not* be represented by the number 2 (the |
| 1886 ASCII code for ^B) or the character `?\^B'. | |
| 1887 | |
| 1888 The `break' key may be represented only by the symbol `break'. | |
| 1889 | |
| 428 | 1890 Mouse button clicks work just like keypresses: (control button1) means |
| 1891 pressing the left mouse button while holding down the control key. | |
| 3086 | 1892 |
| 1893 A string containing the ASCII backspace character, "\\^H", would represent | |
| 1894 two key sequences: `(control h)' and `backspace'. Binding a | |
| 428 | 1895 command to this will actually bind both of those key sequences. Likewise |
| 1896 for the following pairs: | |
| 1897 | |
| 1898 control h backspace | |
| 1899 control i tab | |
| 1900 control m return | |
| 1901 control j linefeed | |
| 1902 control [ escape | |
| 1903 control @ control space | |
| 1904 | |
| 1905 After binding a command to two key sequences with a form like | |
| 1906 | |
| 1907 (define-key global-map "\\^X\\^I" \'command-1) | |
| 1908 | |
| 1909 it is possible to redefine only one of those sequences like so: | |
| 1910 | |
| 1911 (define-key global-map [(control x) (control i)] \'command-2) | |
| 1912 (define-key global-map [(control x) tab] \'command-3) | |

2886 documentation for `lookup-key' for more information. |
| 428 | 2887 |
| 2888 For key-presses, the order of keymaps searched is: | |
| 2889 - the `keymap' property of any extent(s) at point; | |
| 2890 - any applicable minor-mode maps; | |
| 444 | 2891 - the current local map of the current-buffer; |
| 771 | 2892 - either `global-tty-map' or `global-window-system-map', depending on |
| 2893 whether the current console is a TTY or non-TTY console; | |
| 428 | 2894 - the current global map. |
| 2895 | |
| 2896 For mouse-clicks, the order of keymaps searched is: | |
| 2897 - the current-local-map of the `mouse-grabbed-buffer' if any; | |
| 2898 - vertical-divider-map, if the event happened over a vertical divider | |
| 2899 - the `keymap' property of any extent(s) at the position of the click | |
| 2900 (this includes modeline extents); | |
| 2901 - the modeline-map of the buffer corresponding to the modeline under | |
| 2902 the mouse (if the click happened over a modeline); | |
| 444 | 2903 - the value of `toolbar-map' in the current-buffer (if the click |
| 428 | 2904 happened over a toolbar); |
| 444 | 2905 - the current local map of the buffer under the mouse (does not |
| 428 | 2906 apply to toolbar clicks); |
| 2907 - any applicable minor-mode maps; | |
| 771 | 2908 - either `global-tty-map' or `global-window-system-map', depending on |
| 2909 whether the current console is a TTY or non-TTY console; | |
| 428 | 2910 - the current global map. |
| 2911 | |
| 2912 Note that if `overriding-local-map' or `overriding-terminal-local-map' | |
| 2913 is non-nil, *only* those two maps and the current global map are searched. | |
| 771 | 2914 |
| 2915 Note also that key sequences actually received from the keyboard driver | |
| 2916 may be processed in various ways to generate the key sequence that is | |
| 2917 actually looked up in the keymaps. In particular: | |
| 2918 | |
| 2919 -- Keysyms are individually passed through `keyboard-translate-table' before | |
| 2920 any other processing. | |
| 2921 -- After this, key sequences as a whole are passed through | |
| 2922 `key-translation-map'. | |
| 2923 -- The resulting key sequence is actually looked up in the keymaps. | |
| 2924 -- If there's no binding found, the key sequence is passed through | |
| 2925 `function-key-map' and looked up again. | |
| 2926 -- If no binding is found and `retry-undefined-key-binding-unshifted' is | |
| 2927 set (it usually is) and the final keysym is an uppercase character, | |
| 2928 we lowercase it and start over from the `key-translation-map' stage. | |
| 2929 -- If no binding is found and we're on MS Windows and have international | |
| 2930 support, we successively remap the key sequence using the keyboard layouts | |
| 2931 of various default locales (current language environment, user default, | |
| 2932 system default, US ASCII) and try again. This makes (e.g.) sequences | |
| 2933 such as `C-x b' work in a Russian locale, where the alphabetic keys are | |
| 2934 actually generating Russian characters and not the Roman letters written | |
| 2935 on the keycaps. (Not yet implemented) | |
| 2936 -- Finally, if the last keystroke matches `help-char', we automatically | |
| 2937 generate and display a list of possible key sequences and bindings | |
| 2938 given the prefix so far generated. | |

| 3115 when mapping over a keymap, it appears that "x" and "C-x" are in the | |
