/* Here's an overview of how Emacs input works in GUI sessions on
   MS-Windows.  (For description of non-GUI input, see the commentary
   before w32_console_read_socket in w32inevt.c.)

   System messages are read and processed by w32_msg_pump below.  This
   function runs in a separate thread.  It handles a small number of
   custom WM_EMACS_* messages (posted by the main thread, look for
   PostMessage calls), and dispatches the rest to w32_wnd_proc, which
   is the main window procedure for the entire Emacs application.

   w32_wnd_proc also runs in the same separate input thread.  It
   handles some messages, mostly those that need GDI calls, by itself.
   For the others, it calls my_post_msg, which inserts the messages
   into the input queue serviced by w32_read_socket.

   w32_read_socket runs in the main (a.k.a. "Lisp") thread, and is
   called synchronously from keyboard.c when it is known or suspected
   that some input is available.  w32_read_socket either handles
   messages immediately, or converts them into Emacs input events and
   stuffs them into kbd_buffer, where kbd_buffer_get_event can get at
   them and process them when read_char and its callers require
   input.

   Under Cygwin with the W32 toolkit, the use of /dev/windows with
   select(2) takes the place of w32_read_socket.

	   http://search.cpan.org/~ilyaz/UI-KeyboardLayout/lib/UI/KeyboardLayout.pm#Can_an_application_on_Windows_accept_keyboard_events?_Part_IV:_application-specific_modifiers

	 What one needs to find is:
	   * which of the present modifiers AFFECT the resulting char(s)
	     (so should be stripped, since their EFFECT is "already
	      taken into account" in the string in buf), and
	   * which modifiers are not affecting buf, so should be reported to
	     the application for further treatment.

	 Example: assume that we know:
	   (A) lCtrl+rCtrl+rAlt modifiers with VK_A key produce a Latin "f"
	       ("may be logical" in JCUKEN-flavored Russian keyboard flavors);
	   (B) removing any of lCtrl, rCtrl, rAlt changes the produced char;
	   (C) Win-modifier is not affecting the produced character
	       (this is the common case: happens with all "standard" layouts).

	 Suppose the user presses Win+lCtrl+rCtrl+rAlt modifiers with VK_A.
	 What is the intent of the user?  We need to guess the intent to decide
	 which event to deliver to the application.

	 This looks like a reasonable logic: since Win- modifier doesn't affect
	 the output string, the user was pressing Win for SOME OTHER purpose.
	 So the user wanted to generate Win-SOMETHING event.  Now, what is
	 something?  If one takes the mantra that "character payload is more
	 important than the combination of keypresses which resulted in this
	 payload", then one should ignore lCtrl+rCtrl+rAlt, ignore VK_A, and
	 assume that the user wanted to generate Win-f.

	 Unfortunately, without non-destructive ToUnicode(), checking (B),(C)
	 is out of question.  So we use heuristics (hopefully, covering
	 99.9999% of cases).  */

      /* Another thing to watch for is a possibility to use AltGr-* and
	 Ctrl-Alt-* with different semantic.

	 Background: the layout defining the KLLF_ALTGR bit are treated
	 specially by the kernel: when VK_RMENU (=rightAlt, =AltGr) is pressed
	 (released), a press (release) of VK_LCONTROL is emulated (unless Ctrl
	 is already down).  As a result, any press/release of AltGr is seen
	 by applications as a press/release of lCtrl AND rAlt.  This is
	 applicable, in particular, to ToUnicode[Ex]().  (Keyrepeat is covered
	 the same way!)

	   NOTE: it IS possible to see bare rAlt even with KLLF_ALTGR; but this
	   requires a good finger coordination: doing (physically)
	     Down-lCtrl Down-rAlt Up-lCtrl Down-a
	   (doing quick enough, so that key repeat of rAlt [which would
	   generate new "fake" Down-lCtrl events] does not happens before 'a'
	   is down) results in no "fake" events, so the application will see
	   only rAlt down when 'a' is pressed.  (However, fake Up-lCtrl WILL
	   be generated when rAlt goes UP.)

	   In fact, note also that KLLF_ALTGR does not prohibit construction of
	   rCtrl-rAlt (just press them in this order!).

	 Moreover: "traditional" layouts do not define distinct modifier-masks
	 for VK_LMENU and VK_RMENU (same for VK_L/RCONTROL).  Instead, they
	 rely on the KLLF_ALTGR bit to make the behavior of VK_LMENU and
	 VK_RMENU distinct.  As a corollary, for such layouts, the produced
	 character is the same for AltGr-* (=rAlt-*) and Ctrl-Alt-* (in any
	 combination of handedness).  For description of masks, see

	   http://search.cpan.org/~ilyaz/UI-KeyboardLayout/lib/UI/KeyboardLayout.pm#Keyboard_input_on_Windows,_Part_I:_what_is_the_kernel_doing?

	 By default, Emacs was using these coincidences via the following
	 heuristics: it was treating:
	  (*) keypresses with lCtrl-rAlt modifiers as if they are carrying
	      ONLY the character payload (no matter what the actual keyboard
	      was defining: if lCtrl-lAlt-b was delivering U+05df=beta, then
	      Emacs saw [beta]; if lCtrl-lAlt-b was undefined in the layout,
	      the keypress was completely ignored), and
	  (*) keypresses with the other combinations of handedness of Ctrl-Alt
	      modifiers (e.g., lCtrl-lAlt) as if they NEVER carry a character
	      payload (so they were reported "raw": if lCtrl-lAlt-b was
	      delivering beta, then Emacs saw event [C-A-b], and not [beta]).
	 This worked good for "traditional" layouts: users could type both
	 AltGr-x and Ctrl-Alt-x, and one was a character, another a bindable
	 event.

	 However, for layouts which deliver different characters for AltGr-x
	 and lCtrl-lAlt-x, this scheme makes the latter character unaccessible
	 in Emacs.  While it is easy to access functionality of [C-M-x] in
	 Emacs by other means (for example, by the `controlify' prefix, or
	 using lCtrl-rCtrl-x, or rCtrl-rAlt-x [in this order]), missing
	 characters cannot be reconstructed without a tedious manual work.  */

      /* These two cases are often going to be distinguishable, since at most
	 one of these character is defined with KBDCTRL | KBDMENU modifier
	 bitmap.  (This heuristic breaks if both lCtrl-lAlt- AND lCtrl-rAlt-
	 are translated to modifier bitmaps distinct from KBDCTRL | KBDMENU,
	 or in the cases when lCtrl-lAlt-* and lCtrl-rAlt-* are generally
	 different, but lCtrl-lAlt-x and lCtrl-rAlt-x happen to deliver the
	 same character.)

	 So we have 2 chunks of info:
	   (A) is it lCtrl-rAlt-, or lCtrl-lAlt, or some other combination?
	   (B) is the delivered character defined with KBDCTRL | KBDMENU bits?
	 Basing on (A) and (B), we should decide whether to ignore the
	 delivered character.  (Before, Emacs was completely ignoring (B), and
	 was treating the 3-state of (A) as a bit.)  This means that we have 6
	 bits of customization.

	 Additionally, a presence of two Ctrl down may be AltGr-rCtrl-.  */

       doc: /* Get Windows to perform OPERATION on DOCUMENT.
This is a wrapper around the ShellExecute system function, which
invokes the application registered to handle OPERATION for DOCUMENT.

OPERATION is either nil or a string that names a supported operation.
What operations can be used depends on the particular DOCUMENT and its
handler application, but typically it is one of the following common
operations:

 \"open\"    - open DOCUMENT, which could be a file, a directory, or an
	       executable program (application).  If it is an application,
	       that application is launched in the current buffer's default
	       directory.  Otherwise, the application associated with
	       DOCUMENT is launched in the buffer's default directory.
 \"opennew\" - like \"open\", but instruct the application to open
	       DOCUMENT in a new window.
 \"openas\"  - open the \"Open With\" dialog for DOCUMENT.
 \"print\"   - print DOCUMENT, which must be a file.
 \"printto\" - print DOCUMENT, which must be a file, to a specified printer.
	       The printer should be provided in PARAMETERS, see below.
 \"explore\" - start the Windows Explorer on DOCUMENT.
 \"edit\"    - launch an editor and open DOCUMENT for editing; which
	       editor is launched depends on the association for the
	       specified DOCUMENT.
 \"find\"    - initiate search starting from DOCUMENT, which must specify
	       a directory.
 \"delete\"  - move DOCUMENT, a file or a directory, to Recycle Bin.
 \"copy\"    - copy DOCUMENT, which must be a file or a directory, into
	       the clipboard.
 \"cut\"     - move DOCUMENT, a file or a directory, into the clipboard.
 \"paste\"   - paste the file whose name is in the clipboard into DOCUMENT,
	       which must be a directory.
 \"pastelink\"
	   - create a shortcut in DOCUMENT (which must be a directory)
	       the file or directory whose name is in the clipboard.
 \"runas\"   - run DOCUMENT, which must be an executable file, with
	       elevated privileges (a.k.a. \"as Administrator\").
 \"properties\"
	   - open the property sheet dialog for DOCUMENT.
 nil       - invoke the default OPERATION, or \"open\" if default is
	       not defined or unavailable.

DOCUMENT is typically the name of a document file or a URL, but can
also be an executable program to run, or a directory to open in the
Windows Explorer.  If it is a file or a directory, it must be a local
one; this function does not support remote file names.

If DOCUMENT is an executable program, the optional third arg PARAMETERS
can be a string containing command line parameters, separated by blanks,
that will be passed to the program.  Some values of OPERATION also require
parameters (e.g., \"printto\" requires the printer address).  Otherwise,
PARAMETERS should be nil or unspecified.  Note that double quote characters
in PARAMETERS must each be enclosed in 2 additional quotes, as in \"\"\".

Optional fourth argument SHOW-FLAG can be used to control how the
application will be displayed when it is invoked.  If SHOW-FLAG is nil
or unspecified, the application is displayed as if SHOW-FLAG of 10 was
specified, otherwise it is an integer between 0 and 11 representing
a ShowWindow flag:

  0 - start hidden
  1 - start as normal-size window
  3 - start in a maximized window
  6 - start in a minimized window
 10 - start as the application itself specifies; this is the default.  */)

Certain key combinations like Alt-Tab and Win-R are reserved for
system use on Windows, and therefore are normally intercepted by the
system.  These key combinations can be used in Emacs by registering
them as hot-keys, except for Win-L which always locks the computer.

On Windows 98 and ME, KEY must be a one element key definition in
vector form that would be acceptable to `define-key' (e.g. [A-tab] for
Alt-Tab).  The meta modifier is interpreted as Alt if
`w32-alt-is-meta' is t, and hyper is always interpreted as the Windows
modifier keys.  The return value is the hotkey-id if registered,
otherwise nil.

On Windows versions since NT, KEY can also be specified as just a
modifier key, [M-], [s-] or [H-], to indicate that all combinations
of the respective modifier key should be processed by Emacs instead
of the operating system.  The super and hyper modifiers are
interpreted according to the current values of `w32-lwindow-modifier'
and `w32-rwindow-modifier'.  For instance, setting `w32-lwindow-modifier'
to `super' and then calling `(w32-register-hot-key [s-])' grabs all
combinations of the left Windows key to Emacs as keys with the Super
modifier, but leaves the right Windows key free for the operating
system keyboard shortcuts.

The return value is t if the call affected any key combinations,
otherwise nil.  */)

Value is the integer unique ID of the notification that can be used
to remove the notification using `w32-notification-close', which see.
If the function fails, the return value is nil.

Tray notifications, a.k.a. \"taskbar messages\", are messages that
inform the user about events unrelated to the current user activity,
such as a significant system event, by briefly displaying informative
text in a balloon from an icon in the notification area of the taskbar.

Parameters in PARAMS are specified as keyword/value pairs.  All the
parameters are optional, but if no parameters are specified, the
function will do nothing and return nil.

The following parameters are supported:

:icon ICON       -- Display ICON in the system tray.  If ICON is a string,
                    it should specify a file name from which to load the
                    icon; the specified file should be a .ico Windows icon
                    file.  If ICON is not a string, or if this parameter
                    is not specified, the standard Emacs icon will be used.

:tip TIP         -- Use TIP as the tooltip for the notification.  If TIP
                    is a string, this is the text of a tooltip that will
                    be shown when the mouse pointer hovers over the tray
                    icon added by the notification.  If TIP is not a
                    string, or if this parameter is not specified, the
                    default tooltip text is \"Emacs notification\".  The
                    tooltip text can be up to 127 characters long (63
                    on Windows versions before W2K).  Longer strings
                    will be truncated.

:level LEVEL     -- Notification severity level, one of `info',
                    `warning', or `error'.  If given, the value
                    determines the icon displayed to the left of the
                    notification title, but only if the `:title'
                    parameter (see below) is also specified and is a
                    string.

:title TITLE     -- The title of the notification.  If TITLE is a string,
                    it is displayed in a larger font immediately above
                    the body text.  The title text can be up to 63
                    characters long; longer text will be truncated.

:body BODY       -- The body of the notification.  If BODY is a string,
                    it specifies the text of the notification message.
                    Use embedded newlines to control how the text is
                    broken into lines.  The body text can be up to 255
                    characters long, and will be truncated if it's longer.

Note that versions of Windows before W2K support only `:icon' and `:tip'.
You can pass the other parameters, but they will be ignored on those
old systems.

There can be at most one active notification at any given time.  An
active notification must be removed by calling `w32-notification-close'
before a new one can be shown.
