hard-space after coupletnumber? melisma's in lyrics

Is there a way to have more lyrics under the same note? What is the shortcut for a hardspace? (Ctrl-Space is not working here)

You can use Shift-Alt-Space for this.

A hard space is Shift+Alt+Space (like it is in Word, I think).

To have more than one line of lyrics under a note, press down arrow while in the lyrics popover: you will see the line number change from 1 to 2 signifying that you are now inputting into the second line.

Thank you very much!
