This event class contains information about keypress (character) events.
+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
+maintained in a pressed state you will typically get a lot of (automatically
+generated) down events but only one up so it is wrong to assume that there is
+one up event corresponding to each down one.
+
+Both key events provide untranslated key codes while the char event carries
+the translated one. The untranslated code for alphanumeric keys is always
+an upper case value. For the other keys it is one of {\tt WXK\_XXX} values
+from the \helpref{keycodes table}{keycodes}. The translated key is, in
+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.
+
+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
+is {\tt ASCII a} $== 97$. On the other hand, if you press both {\sc Shift} and
+{\tt 'A'} keys simultaneously , the key code in key down event will still be
+just {\tt 'A'} while the char event key code parameter will now be {\tt 'A'}
+as well.
+
+Although in this simple case it is clear that the correct key code could be
+found in the key down event handler by checking the value returned by
+\helpref{ShiftDown()}{wxkeyeventshiftdown}, in general you should use
+{\tt EVT\_CHAR} for this as for non alphanumeric keys the translation is
+keyboard-layout dependent and can only be done properly by the system itself.
+
+Another kind of translation is done when the control key is pressed: for
+example, for {\sc Ctrl-A} key press the key down event still carries the
+same key code {\tt 'a'} as usual but the char event will have key code of
+$1$, the ASCII value of this key combination.
+
+You may discover how the other keys on your system behave interactively by
+running the \helpref{text}{sampletext} wxWidgets sample and pressing some keys
+in any of the text controls shown in it.
+
+{\bf Note:} If a key down ({\tt EVT\_KEY\_DOWN}) event is caught and
+the event handler does not call {\tt event.Skip()} then the coresponding
+char event ({\tt EVT\_CHAR}) will not happen. This is by design and
+enables the programs that handle both types of events to be a bit
+simpler.
+
+{\bf Note for Windows programmers:} The key and char events in wxWidgets are
+similar to but slightly different from Windows {\tt WM\_KEYDOWN} and
+{\tt WM\_CHAR} events. In particular, Alt-x combination will generate a char
+event in wxWidgets (unless it is used as an accelerator).
+
+{\bf Tip:} be sure to call {\tt event.Skip()} for events that you don't process in
+key event function, otherwise menu shortcuts may cease to work under Windows.

+\constfunc{bool}{HasModifiers}{\void}
-\membersection{wxKeyEvent::ShiftDown}
+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

+{\sc Meta} under X but the key presses even while {\sc NumLock} is on should
+be still processed normally).

+\constfunc{bool}{ShiftDown}{\void}
