529 allowed:

530
|

531 channel -- The event channel, a frame or a console. For
|
|
|
532 button-press, button-release, misc-user and motion events,
|
|
|
533 this must be a frame. For key-press events, it must be
|
|
|
534 a console. If channel is unspecified, it will be set to
|
|
|
535 the selected frame or selected console, as appropriate.
|
|
|
536 key -- The event key, a symbol or character. Allowed only for
|
|
|
537 keypress events.
|
|
|
538 button -- The event button, integer 1, 2 or 3. Allowed for
|
|
|
539 button-press, button-release and misc-user events.
|
|
|
540 modifiers -- The event modifiers, a list of modifier symbols. Allowed
|
|
|
541 for key-press, button-press, button-release, motion and
|
|
|
542 misc-user events.
|
|
|
543 function -- Function. Allowed for misc-user events only.
|
|
|
544 object -- An object, function's parameter. Allowed for misc-user
|
|
|
545 events only.
|
|
|
546 x -- The event X coordinate, an integer. This is relative
|
|
|
547 to the left of CHANNEL's root window. Allowed for
|
|
|
548 motion, button-press, button-release and misc-user events.
|
|
|
549 y -- The event Y coordinate, an integer. This is relative
|
|
|
550 to the top of CHANNEL's root window. Allowed for
|
|
|
551 motion, button-press, button-release and misc-user events.
|
|
|
552 timestamp -- The event timestamp, a non-negative integer. Allowed for
|
|
|
553 all types of events. If unspecified, it will be set to 0
|
|
|
554 by default.
|

1212 - a Lisp_Event should contain a keysym AND a character slot.

1213 - keybindings are tried with the keysym. If no binding can be found,

1403 KEY-DESCRIPTION is the first argument, and the event to fill in is the

1405 arguments ``mean'' -- for example, the number 9 is converted to the

1406 character ``Tab'', not the distinct character ``Control-I''.
|

428

1407
|

1408 KEY-DESCRIPTION can be an integer, a character, a symbol such as 'clear,

444
|
1417 If KEY-DESCRIPTION is an integer or character, the high bit may be

|
|

1419 lots of places -- specifically, because lots of Lisp code uses specs like
|
|
|
1420 ?\M-d and "\M-d" in key code, expecting this to work; yet these are in

1421 reality converted directly to 8-bit characters by the Lisp reader.) If

1422 USE-CONSOLE-META-FLAG is nil or CONSOLE is not a TTY, this will always be
|
|
|
1423 the case. If USE-CONSOLE-META-FLAG is non-nil and CONSOLE is a TTY, the
|
|
|
1424 `meta' flag for CONSOLE affects whether the high bit is interpreted as a
|
|
|
1425 meta key. (See `set-input-mode'.) Don't set this flag to non-nil unless
|
|
|
1426 you know what you're doing (more specifically, only if the character came
|
|
|
1427 directly from a TTY, not from the user). If you don't want this silly meta
|
|
|
1428 interpretation done, you should pass in a list containing the character.
|

428
|
1429
|
|
|
1430 Beware that character-to-event and event-to-character are not strictly
|
|

1431 inverse functions, since events contain much more information than the
|
|
444
|
1432 Lisp character object type can encode.

1872
|
|
|
1873 `shift': The Shift key. Will not appear, in general, on key events
|
|
|
1874 where the keysym is an ASCII character, because using Shift
|
|
|
1875 on such a character converts it into another character rather
|
|
|
1876 than actually just adding a Shift modifier.
|
|
|
1877
|
|
|
1878 `control': The Control key.
|
|
|
1879
|
|
|
1880 `meta': The Meta key. On PC's and PC-style keyboards, this is generally
|
|
|
1881 labelled \"Alt\"; Meta is a holdover from early Lisp Machines and
|
|
|
1882 such, propagated through the X Window System. On Sun keyboards,
|
|
|
1883 this key is labelled with a diamond.
|
|
|
1884
|
|
|
1885 `alt': The \"Alt\" key. Alt is in quotes because this does not refer
|
|
|
1886 to what it obviously should refer to, namely the Alt key on PC
|
|
|
1887 keyboards. Instead, it refers to the key labelled Alt on Sun
|
|
|
1888 keyboards, and to no key at all on PC keyboards.
|
|
|
1889
|
|
|
1890 `super': The Super key. Most keyboards don't have any such key, but
|
|
|
1891 under X Windows using `xmodmap' you can assign any key (such as
|
|
|
1892 an underused right-shift, right-control, or right-alt key) to
|
|
|
1893 this key modifier. No support currently exists under MS Windows
|
|
|
1894 for generating these modifiers.
|
|
|
1895
|
|
|
1896 `hyper': The Hyper key. Works just like the Super key.
|
|
|
1897
|
|
|
1898 `button1': The mouse buttons. This means that the specified button was held
|
|
|
1899 `button2': down at the time the event occurred. NOTE: For button-press
|
|
|
1900 `button3': events, the button that was just pressed down does NOT appear in
|
|
|
1901 `button4': the modifiers.
|
|
|
1902 `button5':
|
|
|
1903
|
|
|
1904 Button modifiers are currently ignored when defining and looking up key and
|
|
|
1905 mouse strokes in keymaps. This could be changed, which would allow a user to
|
|
|
1906 create button-chord actions, use a button as a key modifier and do other
|
|
|
1907 clever things.
