A text field can be the first responder without necessarily being the focus of keyboard input. For example, it might be the first responder of window A but window B is the main and key window.

Since a first responder but non-key window text field can't receive input it should not even look like an active text field (Cocoa has a "slightly active" text field look it uses when another window is the key window, but Cappuccino doesn't today.)
It's also possible for a text field to be non-editable but selectable in which case it can also become the first responder -
this is what allows text to be copied from it.
