# Mailboxes, Messages, and Addresses

*Note: This essay assumes basic familiarity with Elm.*

In Elm, signals always have a data source associated with them. `Window.dimensions` is exactly what you think it is, and you can't send your own events on it. You can derive your own signals from these primitives using `map`, `filter`, and `merge`, but the timing of events is beyond your control.

This becomes a problem when you try to add UI elements. We want to be able to add checkboxes and dropdown menus, and to receive the current state of these elements as a signal. So how do we do that?
