You can use this to check your keyboard mappings, for example.
start with:
    EventMonitorView open
and watch the output on xterm.

Caveat:
    This is one of the oldest apps inside ST/X. Don't look too deep into the code...

 redraw

(comment from inherited method)
redraw myself
if there is a model, this one shall redraw itself,
otherwise we cannot do much here - has to be redefined in subclasses

 showEventTime

 buttonMotion: state x: x y: y

(comment from inherited method)
button was moved

 buttonMultiPress: button x: x y: y

(comment from inherited method)
button was pressed quickly again - check my components for a hit.

 buttonPress: button x: x y: y

(comment from inherited method)
button was pressed - check my components for a hit.

 buttonRelease: button x: x y: y

(comment from inherited method)
button was released - check my components for a hit.

 configureX: x y: y width: newWidth height: newHeight

(comment from inherited method)
my size has changed by window manager action

 coveredBy: coveringView

(comment from inherited method)
the receiver has been covered by another view;
we are not interested in that here (but see modalBox for more).

 dispatchEvent: event withFocusOn: focusViewOrNil delegate: doDelegate

Timestamp now printOn:outputStream.

 dropMessage: dropType data: dropData

 focusIn

(comment from inherited method)
got keyboard focus - do nothing here

 focusOut

lost keyboard focus (via the window manager).
Nothing done here

 hasKeyboardFocus: aBoolen

(comment from inherited method)
notification from the windowGroup that I got the keyboardFocus.

 key: key what: pressOrRelease x: x y: y

 keyPress: key x: x y: y

(comment from inherited method)
a key has been pressed. If there are components,
pass it to the corresponding one.
Otherwise, forward it to the superview, if there is any.

 keyRelease: key x: x y: y

(comment from inherited method)
a key has been released. If there are components,
pass it to the corresponding one.
Otherwise, do whatever my superclass would do.

 mapped

(comment from inherited method)
the view has been mapped (by some outside
action - i.e. window manager de-iconified me)

 pointerEnter: state x: x y: y

(comment from inherited method)
mouse pointer entered - request the keyboard focus (sometimes)

 pointerLeave: state

(comment from inherited method)
mouse pointer left

 printKeyInfoFor: key x: x y: y

 sizeChanged: how from: oldExtentOrNil

my view has changed the size (not the contents)

 unmapped

(comment from inherited method)
the view has been unmapped
(either by some outside action - i.e. window manager iconified me,
or due to unmapping of my parentView).

 visibilityChange: how

(comment from inherited method)
the visibility of the view has changed (by some outside
action - i.e. window manager rearranged things).
Using this knowledge avoids useless redraw in obscured views.
