Se puede encontrar una lista general de enlaces y eventos en effbot.org o en los documentos proporcionados por New Mexico Tech, mientras que el nombre de varios keys se enumeran aquí además de la documentación original.
Aquí hay un resumen de los eventos más comunes con algunos nombres de pulsaciones de teclas explicados:
Button 1 is the leftmost button, button 2 is the middle button
(where available), and button 3 the rightmost button.
, , and <1> are all synonyms.
For mouse wheel support under Linux, use Button-4 (scroll
up) and Button-5 (scroll down)
The mouse is moved, with mouse button 1 being held down (use
B2 for the middle button, B3 for the right button).
Button 1 was released. This is probably a better choice in
most cases than the Button event, because if the user
accidentally presses the button, they can move the mouse
off the widget to avoid setting off the event.
Button 1 was double clicked. You can use Double or Triple as
prefixes.
The mouse pointer entered the widget (this event doesn’t mean
that the user pressed the Enter key!).
The mouse pointer left the widget.
Keyboard focus was moved to this widget, or to a child of
this widget.
Keyboard focus was moved from this widget to another widget.
The user pressed the Enter key. For an ordinary 102-key
PC-style keyboard, the special keys are Cancel (the Break
key), BackSpace, Tab, Return(the Enter key), Shift_L (any
Shift key), Control_L (any Control key), Alt_L (any Alt key),
Pause, Caps_Lock, Escape, Prior (Page Up), Next (Page Down),
End, Home, Left, Up, Right, Down, Print, Insert, Delete, F1,
F2, F3, F4, F5, F6, F7, F8, F9, F10, F11, F12, Num_Lock, and
Scroll_Lock.
The user pressed any key. The key is provided in the char
member of the event object passed to the callback (this is an
empty string for special keys).
a The user typed an “a”. Most printable characters can be used
as is. The exceptions are space () and less than
(). Note that 1 is a keyboard binding, while <1> is a
button binding.
The user pressed the Up arrow, while holding the Shift key
pressed. You can use prefixes like Alt, Shift, and Control.
The widget changed size (or location, on some platforms). The
new size is provided in the width and height attributes of
the event object passed to the callback.

Por lo general, para mí, estos módulos se muestran como una pestaña en mi IDE de Wing si ocurre una excepción.
