--  Key_Code - Specifies the key code to translate.
--  Column   - Specifies the element of the key symbol vector for this key code
--             to return.
--
-- Each key code has a list of possible key symbols associated with it.  That
-- list contains only No_Symbol's if the key does not exist.  For keys that
-- exist the first element of the list (0'th) is the unshifted key name.
-- The second element (1'st) is the shifted key name.  See section 7.9 of the
-- MIT X Library manual ("Keyboard Encoding") for details.

------------------------------------------------------------------------------
--  Display    - Specifies the X_Display context to use in the translation.
--  Key_Symbol - Specifies the key symbol to be searched out.
--
-- Returns the key code corresponding to the specified key symbol.  (There may
-- be more than one such key code; the first found is returned.)  Returns 0 if
-- there is no such key for this server/keyboard.
------------------------------------------------------------------------------

    function X_Key_Sym_To_String (Key_Symbol : X_Key_Sym) return X_String;
------------------------------------------------------------------------------
--  Key_Symbol - Specifies the key symbol to be named.
--

-- symbol.

------------------------------------------------------------------------------
--  Event  - Specifies the Event containing the key-stroke to be translated.
--  Column - Specifies the index into the key symbol table.
--
-- Uses a given keyboard event and the index specified to return the key symbol
-- corresponding to the key code recorded in the event.  The event has an
-- associated X_Display.  That display's key symbol table is used for the
-- lookup.

------------------------------------------------------------------------------
--  Event      - Specifies the Event containing the key-stroke to be translated.
--               This indirectly specifies the X_Display which in turn specifies
--               the key symbol table to be used to make the translation.
--  Buffer     - Receives the translated characters.
--  Result     - Receives the number of characters used in the Buffer by the
--              translation.
--  Key_Symbol - Receives the key symbol computed from the event.
--  Status     - Specifies an X_Compose_Status record.
--
-- Maps a key event into an 8-bit Ascii string.

------------------------------------------------------------------------------
--  Display       - Specifies the X_Display context to rebind within.
--  Key_Symbol    - Specifies the key symbol being rebound.
--  Modifier_List - Specifies the key symbols which are the modifiers associated
--                  with the key-chord being rebound.
--  Binding       - Specifies the the 8-bit Ascii string to be associated with
--                  the rebound key-chord.
--
-- Rebinds, within this application, the meaning of a particular
-- key-chord (a key symbol with zero or more modifiers) for all display
-- connections.  X_Lookup_String will return this string when called with a
-- key event representing this chord.  This provides an easy way to bind
-- long strings to keys.
------------------------------------------------------------------------------

    function X_String_To_Key_Sym (Name : X_String) return X_Key_Sym;
------------------------------------------------------------------------------
--  Name - Specifies the name of the key symbol to convert.
--
-- Converts the name of a key symbol to the associated key symbol code.  Returns
-- No_Symbol if S is not the name of a valid key symbol.
------------------------------------------------------------------------------

    procedure X_Refresh_Keyboard_Mapping (Event : X_Event);
------------------------------------------------------------------------------
--  Event     - Specifies the event that caused the procedure call.  Typically
--             this is a Mapping_Notify event.
--
-- Refreshes the stored modifier and keymap information.  The information is
-- stored on a per-X_Display basis.  The Event has an associated X_Display and
-- that X_Display has its tables refreshed.
