That makes sense to me, too.

However, you didn't do it that way when you wrote PluggableListMorph>>

keyStroke: event 
	"Process keys 
	specialKeys are things like up, down, etc. ALWAYS HANDLED 
	modifierKeys are regular characters either 1) accompanied with ctrl, 
	cmd or 2) any character if the list doesn't want to handle basic 
	keys (handlesBasicKeys returns false) 
	basicKeys are any characters"
	| aChar aSpecialKey |
	(self scrollByKeyboard: event) ifTrue: [^self].
	aChar _ event keyCharacter.
	aSpecialKey _ aChar asciiValue.
	aSpecialKey < 32 ifTrue: [^ self specialKeyPressed: aSpecialKey].
	(event anyModifierKeyPressed or: [self handlesBasicKeys not])
		ifTrue: [^ self modifierKeyPressed: aChar].
	^ self basicKeyPressed: aChar

The first time your code looks at the keystrokeActionSelector is in 

Did you have a change of heart?
