31 * A key press or release. Down-flag is non-zero (true) if the key is now pressed, zero
32 * (false) if it is now released. The key itself is specified using the “keysym” values
33 * defined by the X Window System.
34 * 1 - U8 - message-type
35 * 1 - U8 - down-flag
36 * 2 - - - padding
37 * 4 - U32 - key
38 * For most ordinary keys, the “keysym” is the same as the corresponding ASCII value.
39 * For full details, see The Xlib Reference Manual, published by O’Reilly & Associates,
40 * or see the header file <X11/keysymdef.h> from any X Window System installa-
41 * tion.
