| 513 channel -- The event channel, a frame or a console. For | |
| 514 button-press, button-release, misc-user and motion events, | |
| 515 this must be a frame. For key-press events, it must be | |
| 516 a console. If channel is unspecified, it will be set to | |
| 517 the selected frame or selected console, as appropriate. | |
| 518 key -- The event key, a symbol or character. Allowed only for | |
| 519 keypress events. | |
| 520 button -- The event button, integer 1, 2 or 3. Allowed for | |
| 521 button-press, button-release and misc-user events. | |
| 522 modifiers -- The event modifiers, a list of modifier symbols. Allowed | |
| 523 for key-press, button-press, button-release, motion and | |
| 524 misc-user events. | |
| 525 function -- Function. Allowed for misc-user events only. | |
| 526 object -- An object, function's parameter. Allowed for misc-user | |
| 527 events only. | |
| 528 x -- The event X coordinate, an integer. This is relative | |
| 529 to the left of CHANNEL's root window. Allowed for | |
| 530 motion, button-press, button-release and misc-user events. | |
| 531 y -- The event Y coordinate, an integer. This is relative | |
| 532 to the top of CHANNEL's root window. Allowed for | |
| 533 motion, button-press, button-release and misc-user events. | |
| 534 timestamp -- The event timestamp, a non-negative integer. Allowed for | |
| 535 all types of events. If unspecified, it will be set to 0 | |
| 536 by default. | |
| 537 | |
| 538 For event type `empty', PLIST must be nil. | |

| 1204 | 1176 DO_BACKSPACE_MAPPING means that if CON is a TTY, and C is a the TTY's |
| 1177 backspace character, the event will have keysym `backspace' instead of | |
| 1178 '(control h). It is clearly correct to do this conversion is the | |
| 1179 character was just read from a TTY, clearly incorrect inside of | |
| 1180 define-key, which must be able to handle all consoles. #### What about | |
| 1181 in other circumstances? #### Should the user have access to this flag? | |
| 1182 | |
| 1183 #### We need to go through and review all the flags in | |
| 1184 character_to_event() and event_to_character() and figure out exactly | |
| 1185 under what circumstances they should or should not be set, then go | |
| 1186 through and review all callers of character_to_event(), | |
| 1187 Fcharacter_to_event(), event_to_character(), and Fevent_to_character() | |
| 1188 and check that they are passing the correct flags in for their varied | |
| 1189 circumstances. | |
| 1190 | |
| 1191 #### Some of this garbage, and some of the flags, could go away if we | |
| 1192 implemented the suggestion, originally from event-Xt.c: | |
| 1193 | |
| 2828 | 1194 [[ The way that keysym correspondence to characters should work: |
| 1204 | 1195 - a Lisp_Event should contain a keysym AND a character slot. |
| 1196 - keybindings are tried with the keysym. If no binding can be found, | |
| 2828 | 1197 and there is a corresponding character, call self-insert-command. ]] |
| 1198 | |
| 1199 That's an X-specific way of thinking. All the other platforms--even | |
| 1200 the TTY, make sure you've done (set-input-mode t nil 1) and set your | |
| 1201 console coding system appropriately when checking--just use | |
| 1202 characters as emacs keysyms, and, together with defaulting to | |
| 1203 self-insert-command if an unbound key with a character correspondence | |
| 1204 is typed, that works fine for them. (Yes, this ignores GTK.) | |
| 1205 | |
| 1206 [[ [... snipping other suggestions which I've implemented.] | |
| 1207 Nuke the Qascii_character property. ]] | |
| 1204 | 1208 |
| 2828 | 1209 Well, we've renamed it anyway--it was badly named. |
| 1210 Qcharacter_of_keysym, here we go. It's really only with X11 that how | |
| 1211 to map between adiaeresis and (int-to-char #xE4), or ellipsis and | |
| 1212 whatever, becomes an issue, and IMO the property approach to this is | |
| 1213 fine. Aidan Kehoe, 2005-05-15. | |
| 1204 | 1214 |
| 2828 | 1215 [[ This would apparently solve a lot of different problems. ]] |
| 1216 | |
| 1217 I'd be interested to know what's left. Removing the allow-meta | |
| 1218 argument from event-to-character would be a Good Thing, IMO, but | |
| 1219 beyond that, I'm not sure what else there is to do wrt. key | |
| 1220 mappings. Of course, feedback from users of the Russian C-x facility | |
| 1221 is still needed. */ | |

| 444 | 1397 KEY-DESCRIPTION is the first argument, and the event to fill in is the |
| 1398 second. This function contains knowledge about what various kinds of | |
| 1399 arguments ``mean'' -- for example, the number 9 is converted to the | |
| 1400 character ``Tab'', not the distinct character ``Control-I''. | |
| 428 | 1401 |
| 3025 | 1402 KEY-DESCRIPTION can be an integer, a character, a symbol such as `clear', |

| 444 | 1411 If KEY-DESCRIPTION is an integer or character, the high bit may be |
| 1204 | 1412 interpreted as the meta key. (This is done for backward compatibility in |
| 1413 lots of places -- specifically, because lots of Lisp code uses specs like | |
| 1414 ?\M-d and "\M-d" in key code, expecting this to work; yet these are in | |
| 1415 reality converted directly to 8-bit characters by the Lisp reader.) If | |
| 1416 USE-CONSOLE-META-FLAG is nil or CONSOLE is not a TTY, this will always be | |
| 1417 the case. If USE-CONSOLE-META-FLAG is non-nil and CONSOLE is a TTY, the | |
| 1418 `meta' flag for CONSOLE affects whether the high bit is interpreted as a | |
| 1419 meta key. (See `set-input-mode'.) Don't set this flag to non-nil unless | |
| 1420 you know what you're doing (more specifically, only if the character came | |
| 1421 directly from a TTY, not from the user). If you don't want this silly meta | |
| 1422 interpretation done, you should pass in a list containing the character. | |
| 428 | 1423 |
| 1424 Beware that character-to-event and event-to-character are not strictly | |
| 1425 inverse functions, since events contain much more information than the | |
| 444 | 1426 Lisp character object type can encode. |

| 1871 than actually just adding a Shift modifier. | |

| 1873 `control': The Control key. | |
| 1874 | |
| 1875 `meta': The Meta key. On PC's and PC-style keyboards, this is generally | |
| 1876 labelled \"Alt\"; Meta is a holdover from early Lisp Machines and | |
| 1877 such, propagated through the X Window System. On Sun keyboards, | |
| 1878 this key is labelled with a diamond. | |
| 1879 | |
| 1880 `alt': The \"Alt\" key. Alt is in quotes because this does not refer | |
| 1881 to what it obviously should refer to, namely the Alt key on PC | |
| 1882 keyboards. Instead, it refers to the key labelled Alt on Sun | |
| 1883 keyboards, and to no key at all on PC keyboards. | |
| 1884 | |
| 1885 `super': The Super key. Most keyboards don't have any such key, but | |
| 1886 under X Windows using `xmodmap' you can assign any key (such as | |
| 1887 an underused right-shift, right-control, or right-alt key) to | |
| 1888 this key modifier. No support currently exists under MS Windows | |
| 1889 for generating these modifiers. | |
| 1890 | |
| 1891 `hyper': The Hyper key. Works just like the Super key. | |
| 1892 | |
| 1893 `button1': The mouse buttons. This means that the specified button was held | |
| 1894 `button2': down at the time the event occurred. NOTE: For button-press | |
| 1895 `button3': events, the button that was just pressed down does NOT appear in | |
| 1896 `button4': the modifiers. | |
| 1897 `button5': | |
| 1898 | |
| 1899 Button modifiers are currently ignored when defining and looking up key and | |
| 1900 mouse strokes in keymaps. This could be changed, which would allow a user to | |
| 1901 create button-chord actions, use a button as a key modifier and do other | |
