 Defining interactions between presenters is done in the `connectPresenters` method. We implement it to define that, when an element of the list is selected, we should display the information in the detail presenter.
 It is worth taking some time to look at `whenSelectionChangedDo:` message.
 
-The `whenSelectionChangedDo:` method expects a block with zero or one argument. Such an argument is not the selected item directly but a more complex object that represents the selection. Indeed a selection is different in a single item selection list and a multiple selection list. Therefore Spec 20 defines the notion of selection mode under the form of subclasses of `SpAbstractSelectionMode`.

 With transmissions, each presenter can define a set of output ports (ports to transmit information) and input ports (ports to receive information). Widget presenters already have defined the output/input ports you can use with them, but you can add your own ports to your presenters.

-Contrary to Spec 1, in Spec 20 all the layouts are dynamic. It means that you can change on the fly the elements displayed. It is a radical improvement from Spec1 where most of the layouts were static and building dynamic widgets was cumbersome.

 In this chapter, we will show that presenters can be dynamically composed using layouts. We will show a little interactive section. Then we will build a little code editor with dynamic aspects. Note that In this post, we are going to use simply Spec, to refer to Spec 20 when we do not need to stress a difference.
