Sure; pretty much any fltk widget (including the windows themselves) can be
associated with a callback.
So for a Fl_Input you can set the when() as FL_WHEN_ENTER_KEY, then if you hit
the enter key, the callback for the input widget should run.

Can you clarify; I'm not clear what you are asking here, can you outline what
you are trying to achieve, then we can suggest some ways you might implement
that.
Anyway, here's a little fluid file that might show how the enter key stuff
works...

fflush(stdout);
brws->add( input_widget->value());}

}
