Select next label, then Select Time, Start Time 0, End time of 2, 
Relative to selection Start.

Then apply Silence.

Silence with no selection is in one sense undefined behaviour.  I think 
generators *should* be used with selections.  I don't think we have to 
pop up an error message if there was no selection. What you describe 
does not sound bad to me either.
