+// Mapping of X keysyms to and from Windows VK codes.  Ordering here must be
+// such that when we look up a Windows VK code we get the preferred X keysym.
+// Going the other way there is no problem because an X keysym always maps to
+// exactly one Windows VK code.  This map only contain keys which are not the
+// normal keys for printable ASCII characters.  For example it does not contain
+// VK_SPACE (note that things like VK_ADD are for the plus key on the keypad,
+// not on the main keyboard).
