public B sharedKeyBinding() {
		this.keyBindingType = KeyBindingType.SHARED;
		return self();
	}
Marks this action as one that shares a key binding with other actions in the tool.  This
allows multiple clients to supply actions that use the same key binding, each working
within its respective action context.  See {@link KeyBindingType}.

<p>Actions are not shared by default; they are {@link KeyBindingType#INDIVIDUAL}.  This 
means that each action must have its key binding assigned individually.
