Question about making Multiplets

Hi

I'm aware of the "control + #" method. My problem is, what if I'm inputting more than 9?

I don't even know the term for it, but triplet refers to 3 notes, and quintuplet refers to 5 notes right? What if I want 11 notes (I suppose the term should be sth. + uplet)? "Control + #" doesn't work for this, so what should I do?

Thanks!
