|

376 TYPE is a symbol, either `empty', `key-press', `button-press',

377 `button-release', `misc-user' or `motion'. If TYPE is nil, it
|

380 PLIST is a property list, the properties being compatible to those
|

381 returned by `event-properties'. The following properties are
|
|
|
382 allowed:
|
|
|
383
|
|
|
384 channel -- The event channel, a frame or a console. For
|
|
|
385 button-press, button-release, misc-user and motion events,
|
|
|
386 this must be a frame. For key-press events, it must be
|
|
|
387 a console. If channel is unspecified, it will be set to
|
|
|
388 the selected frame or selected console, as appropriate.
|
|
|
389 key -- The event key, a symbol or character. Allowed only for
|
|
|
390 keypress events.
|
|
|
391 button -- The event button, integer 1, 2 or 3. Allowed for
|
|
|
392 button-press, button-release and misc-user events.
|
|
|
393 modifiers -- The event modifiers, a list of modifier symbols. Allowed
|
|
|
394 for key-press, button-press, button-release, motion and
|
|
|
395 misc-user events.
|
|
|
396 function -- Function. Allowed for misc-user events only.
|
|
|
397 object -- An object, function's parameter. Allowed for misc-user
|
|
|
398 events only.
|
|
|
399 x -- The event X coordinate, an integer. This is relative
|
|
|
400 to the left of CHANNEL's root window. Allowed for
|
|
|
401 motion, button-press, button-release and misc-user events.
|
|
|
402 y -- The event Y coordinate, an integer. This is relative
|
|
|
403 to the top of CHANNEL's root window. Allowed for
|
|
|
404 motion, button-press, button-release and misc-user events.
|
|
|
405 timestamp -- The event timestamp, a non-negative integer. Allowed for
|
|
|
406 all types of events. If unspecified, it will be set to 0
|
|
|
407 by default.
|
|
|
408
|
|
|
409 For event type `empty', PLIST must be nil.
|

410 `button-release', or `motion'. If TYPE is left out, it defaults to
|
|
|
411 `empty'.
|

412 PLIST is a list of properties, as returned by `event-properties'. Not
|

413 all properties are allowed for all kinds of events, and some are

1152 arguments ``mean'' -- for example, the number 9 is converted to the

1164 If KEY-DESCRIPTION is an integer or character, the high bit may be

1168 CONSOLE affects whether the high bit is interpreted as a meta

1173 Beware that character-to-event and event-to-character are not strictly

1175 Lisp character object type can encode.

1582
|
|
|
1583 `shift': The Shift key. Will not appear, in general, on key events
|
|
|
1584 where the keysym is an ASCII character, because using Shift
|
|
|
1585 on such a character converts it into another character rather
|
|
|
1586 than actually just adding a Shift modifier.
|
|
|
1587
|
|
|
1588 `control': The Control key.
|
|
|
1589
|
|
|
1590 `meta': The Meta key. On PC's and PC-style keyboards, this is generally
|
|
|
1591 labelled \"Alt\"; Meta is a holdover from early Lisp Machines and
|
|
|
1592 such, propagated through the X Window System. On Sun keyboards,
|
|
|
1593 this key is labelled with a diamond.
|
|
|
1594
|
|
|
1595 `alt': The \"Alt\" key. Alt is in quotes because this does not refer
|
|
|
1596 to what it obviously should refer to, namely the Alt key on PC
|
|
|
1597 keyboards. Instead, it refers to the key labelled Alt on Sun
|
|
|
1598 keyboards, and to no key at all on PC keyboards.
|
|
|
1599
|
|
|
1600 `super': The Super key. Most keyboards don't have any such key, but
|
|
|
1601 under X Windows using `xmodmap' you can assign any key (such as
|
|
|
1602 an underused right-shift, right-control, or right-alt key) to
|
|
|
1603 this key modifier. No support currently exists under MS Windows
|
|
|
1604 for generating these modifiers.
|
|
|
1605
|
|
|
1606 `hyper': The Hyper key. Works just like the Super key.
|
|
|
1607
|
|
|
1608 `button1': The mouse buttons. This means that the specified button was held
|
|
|
1609 `button2': down at the time the event occurred. NOTE: For button-press
|
|
|
1610 `button3': events, the button that was just pressed down does NOT appear in
|
|
|
1611 `button4': the modifiers.
|
|
|
1612 `button5':
|
|
|
1613
|
|
|
1614 Button modifiers are currently ignored when defining and looking up key and
|
|
|
1615 mouse strokes in keymaps. This could be changed, which would allow a user to
|
|
|
1616 create button-chord actions, use a button as a key modifier and do other
|
|
|
1617 clever things.
