| 509 channel -- The event channel, a frame or a console. For | |
| 510 button-press, button-release, misc-user and motion events, | |
| 511 this must be a frame. For key-press events, it must be | |
| 512 a console. If channel is unspecified, it will be set to | |
| 513 the selected frame or selected console, as appropriate. | |
| 514 key -- The event key, a symbol or character. Allowed only for | |
| 515 keypress events. | |
| 516 button -- The event button, integer 1, 2 or 3. Allowed for | |
| 517 button-press, button-release and misc-user events. | |
| 518 modifiers -- The event modifiers, a list of modifier symbols. Allowed | |
| 519 for key-press, button-press, button-release, motion and | |
| 520 misc-user events. | |
| 521 function -- Function. Allowed for misc-user events only. | |
| 522 object -- An object, function's parameter. Allowed for misc-user | |
| 523 events only. | |
| 524 x -- The event X coordinate, an integer. This is relative | |
| 525 to the left of CHANNEL's root window. Allowed for | |
| 526 motion, button-press, button-release and misc-user events. | |
| 527 y -- The event Y coordinate, an integer. This is relative | |
| 528 to the top of CHANNEL's root window. Allowed for | |
| 529 motion, button-press, button-release and misc-user events. | |
| 530 timestamp -- The event timestamp, a non-negative integer. Allowed for | |
| 531 all types of events. If unspecified, it will be set to 0 | |
| 532 by default. | |
| 533 | |
| 534 For event type `empty', PLIST must be nil. | |

| 1204 | 1172 DO_BACKSPACE_MAPPING means that if CON is a TTY, and C is a the TTY's |
| 1173 backspace character, the event will have keysym `backspace' instead of | |
| 1174 '(control h). It is clearly correct to do this conversion is the | |
| 1175 character was just read from a TTY, clearly incorrect inside of | |
| 1176 define-key, which must be able to handle all consoles. #### What about | |
| 1177 in other circumstances? #### Should the user have access to this flag? | |
| 1178 | |
| 1179 #### We need to go through and review all the flags in | |
| 1180 character_to_event() and event_to_character() and figure out exactly | |
| 1181 under what circumstances they should or should not be set, then go | |
| 1182 through and review all callers of character_to_event(), | |
| 1183 Fcharacter_to_event(), event_to_character(), and Fevent_to_character() | |
| 1184 and check that they are passing the correct flags in for their varied | |
| 1185 circumstances. | |
| 1186 | |
| 1187 #### Some of this garbage, and some of the flags, could go away if we | |
| 1188 implemented the suggestion, originally from event-Xt.c: | |
| 1189 | |
| 2828 | 1190 [[ The way that keysym correspondence to characters should work: |
| 1204 | 1191 - a Lisp_Event should contain a keysym AND a character slot. |
| 1192 - keybindings are tried with the keysym. If no binding can be found, | |
| 2828 | 1193 and there is a corresponding character, call self-insert-command. ]] |
| 1194 | |
| 1195 That's an X-specific way of thinking. All the other platforms--even | |
| 1196 the TTY, make sure you've done (set-input-mode t nil 1) and set your | |
| 1197 console coding system appropriately when checking--just use | |
| 1198 characters as emacs keysyms, and, together with defaulting to | |
| 1199 self-insert-command if an unbound key with a character correspondence | |
| 1200 is typed, that works fine for them. (Yes, this ignores GTK.) | |
| 1201 | |
| 1202 [[ [... snipping other suggestions which I've implemented.] | |
| 1203 Nuke the Qascii_character property. ]] | |
| 1204 | 1204 |
| 2828 | 1205 Well, we've renamed it anyway--it was badly named. |
| 1206 Qcharacter_of_keysym, here we go. It's really only with X11 that how | |
| 1207 to map between adiaeresis and (int-to-char #xE4), or ellipsis and | |
| 1208 whatever, becomes an issue, and IMO the property approach to this is | |
| 1209 fine. Aidan Kehoe, 2005-05-15. | |
| 1204 | 1210 |
| 2828 | 1211 [[ This would apparently solve a lot of different problems. ]] |
| 1212 | |
| 1213 I'd be interested to know what's left. Removing the allow-meta | |
| 1214 argument from event-to-character would be a Good Thing, IMO, but | |
| 1215 beyond that, I'm not sure what else there is to do wrt. key | |
| 1216 mappings. Of course, feedback from users of the Russian C-x facility | |
| 1217 is still needed. */ | |

| 1395 arguments ``mean'' -- for example, the number 9 is converted to the | |
| 1396 character ``Tab'', not the distinct character ``Control-I''. | |
| 428 | 1397 |
| 3025 | 1398 KEY-DESCRIPTION can be an integer, a character, a symbol such as `clear', |

| 444 | 1407 If KEY-DESCRIPTION is an integer or character, the high bit may be |
| 1204 | 1408 interpreted as the meta key. (This is done for backward compatibility in |
| 1409 lots of places -- specifically, because lots of Lisp code uses specs like | |
| 1410 ?\M-d and "\M-d" in key code, expecting this to work; yet these are in | |
| 1411 reality converted directly to 8-bit characters by the Lisp reader.) If | |
| 1412 USE-CONSOLE-META-FLAG is nil or CONSOLE is not a TTY, this will always be | |
| 1413 the case. If USE-CONSOLE-META-FLAG is non-nil and CONSOLE is a TTY, the | |
| 1414 `meta' flag for CONSOLE affects whether the high bit is interpreted as a | |
| 1415 meta key. (See `set-input-mode'.) Don't set this flag to non-nil unless | |
| 1416 you know what you're doing (more specifically, only if the character came | |
| 1417 directly from a TTY, not from the user). If you don't want this silly meta | |
| 1418 interpretation done, you should pass in a list containing the character. | |
| 428 | 1419 |
| 1420 Beware that character-to-event and event-to-character are not strictly | |
| 1421 inverse functions, since events contain much more information than the | |
| 444 | 1422 Lisp character object type can encode. |

| 1867 than actually just adding a Shift modifier. | |

| 1869 `control': The Control key. | |
| 1870 | |
| 1871 `meta': The Meta key. On PC's and PC-style keyboards, this is generally | |
| 1872 labelled \"Alt\"; Meta is a holdover from early Lisp Machines and | |
| 1873 such, propagated through the X Window System. On Sun keyboards, | |
| 1874 this key is labelled with a diamond. | |
| 1875 | |
| 1876 `alt': The \"Alt\" key. Alt is in quotes because this does not refer | |
| 1877 to what it obviously should refer to, namely the Alt key on PC | |
| 1878 keyboards. Instead, it refers to the key labelled Alt on Sun | |
| 1879 keyboards, and to no key at all on PC keyboards. | |
| 1880 | |
| 1881 `super': The Super key. Most keyboards don't have any such key, but | |
| 1882 under X Windows using `xmodmap' you can assign any key (such as | |
| 1883 an underused right-shift, right-control, or right-alt key) to | |
| 1884 this key modifier. No support currently exists under MS Windows | |
| 1885 for generating these modifiers. | |
| 1886 | |
| 1887 `hyper': The Hyper key. Works just like the Super key. | |
| 1888 | |
| 1889 `button1': The mouse buttons. This means that the specified button was held | |
| 1890 `button2': down at the time the event occurred. NOTE: For button-press | |
| 1891 `button3': events, the button that was just pressed down does NOT appear in | |
| 1892 `button4': the modifiers. | |
| 1893 `button5': | |
| 1894 | |
| 1895 Button modifiers are currently ignored when defining and looking up key and | |
| 1896 mouse strokes in keymaps. This could be changed, which would allow a user to | |
| 1897 create button-chord actions, use a button as a key modifier and do other | |
