|
|

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

987 returned by `event-properties'. The following properties are
|
|
|
988 allowed:
|
|
|
989
|
|
|
990 channel -- The event channel, a frame or a console. For
|
|
|
991 button-press, button-release, misc-user and motion events,
|
|
|
992 this must be a frame. For key-press events, it must be
|
|
|
993 a console. If channel is unspecified, it will be set to
|
|
|
994 the selected frame or selected console, as appropriate.
|
|
|
995 key -- The event key, a symbol or character. Allowed only for
|
|
|
996 keypress events.
|
|
|
997 button -- The event button, integer 1, 2 or 3. Allowed for
|
|
|
998 button-press, button-release and misc-user events.
|
|
|
999 modifiers -- The event modifiers, a list of modifier symbols. Allowed
|
|
|
1000 for key-press, button-press, button-release, motion and
|
|
|
1001 misc-user events.
|
|
|
1002 function -- Function. Allowed for misc-user events only.
|
|
|
1003 object -- An object, function's parameter. Allowed for misc-user
|
|
|
1004 events only.
|
|
|
1005 x -- The event X coordinate, an integer. This is relative
|
|
|
1006 to the left of CHANNEL's root window. Allowed for
|
|
|
1007 motion, button-press, button-release and misc-user events.
|
|
|
1008 y -- The event Y coordinate, an integer. This is relative
|
|
|
1009 to the top of CHANNEL's root window. Allowed for
|
|
|
1010 motion, button-press, button-release and misc-user events.
|
|
|
1011 timestamp -- The event timestamp, a non-negative integer. Allowed for
|
|
|
1012 all types of events. If unspecified, it will be set to 0
|
|
|
1013 by default.
|
|
|
1014

2145 arguments ``mean'' -- for example, the number 9 is converted to the

2147
|

2161 CONSOLE affects whether the high bit is interpreted as a meta

2168 Lisp character object type can encode.

2660 Return a list of symbols, the names of the modifier keys and buttons
|
|
428
|
2661 which were down when the given mouse or keyboard event was produced.
|
|
442
|
2662 See also the function `event-modifier-bits'.
|
|
|
2663
|
|
|
2664 The possible symbols in the list are
|
|
|
2665
|
|
|
2666 `shift': The Shift key. Will not appear, in general, on key events
|
|
|
2667 where the keysym is an ASCII character, because using Shift
|
|
|
2668 on such a character converts it into another character rather
|
|
|
2669 than actually just adding a Shift modifier.
|
|
|
2670
|
|
|
2671 `control': The Control key.
|
|
|
2672
|
|
|
2673 `meta': The Meta key. On PC's and PC-style keyboards, this is generally
|
|
|
2674 labelled \"Alt\"; Meta is a holdover from early Lisp Machines and
|
|
|
2675 such, propagated through the X Window System. On Sun keyboards,
|
|
|
2676 this key is labelled with a diamond.
|
|
|
2677
|
|
|
2678 `alt': The \"Alt\" key. Alt is in quotes because this does not refer
|
|
|
2679 to what it obviously should refer to, namely the Alt key on PC
|
|
|
2680 keyboards. Instead, it refers to the key labelled Alt on Sun
|
|
|
2681 keyboards, and to no key at all on PC keyboards.
|
|
|
2682
|
|
|
2683 `super': The Super key. Most keyboards don't have any such key, but
|
|
|
2684 under X Windows using `xmodmap' you can assign any key (such as
|
|
|
2685 an underused right-shift, right-control, or right-alt key) to
|
|
|
2686 this key modifier. No support currently exists under MS Windows
|
|
|
2687 for generating these modifiers.
|
|
|
2688
|
|
|
2689 `hyper': The Hyper key. Works just like the Super key.
|
|
|
2690
|
|
|
2691 `button1': The mouse buttons. This means that the specified button was held
|
|
|
2692 `button2': down at the time the event occurred. NOTE: For button-press
|
|
|
2693 `button3': events, the button that was just pressed down does NOT appear in
|
|
|
2694 `button4': the modifiers.
|
|
|
2695 `button5':
|
|
|
2696
|
|
|
2697 Button modifiers are currently ignored when defining and looking up key and
|
|
|
2698 mouse strokes in keymaps. This could be changed, which would allow a user to
|
|
|
2699 create button-chord actions, use a button as a key modifier and do other
|
|
|
2700 clever things.
