+Notice that there are three different kinds of keyboard events in wxWidgets:
key down and up events and char events. The difference between the first two
is clear - the first corresponds to a key press and the second to a key
release - otherwise they are identical. Just note that if the key is
general, the character the user expects to appear as the result of the key
combination when typing the text into a text entry zone, for example.
-If the key up event is caught and the event handler does not call
-event.Skip() then the coresponding char event will not happen. This
-is by design and enables the programs that handle both types of events
-to be a bit simpler.
-
A few examples to clarify this (all assume that {\sc Caps Lock} is unpressed
and the standard US keyboard): when the {\tt 'A'} key is pressed, the key down
event key code is equal to {\tt ASCII A} $== 65$. But the char event key code
$1$, the ASCII value of this key combination.
You may discover how the other keys on your system behave interactively by

-\membersection{wxKeyEvent::ControlDown}
+\constfunc{bool}{CmdDown}{\void}
+
+"Cmd" is a pseudo key which is the same as Control for PC and Unix platforms
+but the special "Apple" (a.k.a as "Command") key under Macs: it makes often
+sense to use it instead of, say, ControlDown() because Cmd key is used for the
+same thing under Mac as Ctrl elsewhere (but Ctrl still exists, just not used
+for this purpose under Mac). So for non-Mac platforms this is the same as
+\helpref{ControlDown()}{wxkeyeventcontroldown} and under Mac this is the same
+as \helpref{MetaDown()}{wxkeyeventmetadown}.
+

+\membersection{wxKeyEvent::ControlDown}\label{wxkeyeventcontroldown}
\constfunc{bool}{ControlDown}{\void}

\membersection{wxKeyEvent::GetKeyCode}
while non-ASCII events return values such as {\bf WXK\_LEFT} for the
left cursor key. See \helpref{Keycodes}{keycodes} for a full list of the virtual key codes.

-\constfunc{bool}{MetaDown}{\void}
+\constfunc{wxUint32}{GetRawKeyCode}{\void}

+Returns the raw key code for this event. This is a platform-dependent scan code
+which should only be used in advanced applications.
-\membersection{wxKeyEvent::GetPosition}

+\membersection{wxKeyEvent::GetRawKeyFlags}

+\membersection{wxKeyEvent::GetUnicodeKey}
+
+\constfunc{wxChar}{GetUnicodeKey}{\void}

\constfunc{bool}{HasModifiers}{\void}
-Returns TRUE if either {\sc Ctrl} or {\sc Alt} keys was down
+Returns true if either {\sc Ctrl} or {\sc Alt} keys was down
at the time of the key event. Note that this function does not take into
account neither {\sc Shift} nor {\sc Meta} key states (the reason for ignoring
the latter is that it is common for {\sc NumLock} key to be configured as
{\sc Meta} under X but the key presses even while {\sc NumLock} is on should
be still processed normally).
