Paperfontsize

[Philipp Vetter]

Hello,

 My question is: how can I change the paperfontsize to 9 pt?
 Lyx only seems to give me the options default, 10,11 or 12 pt.
I am writing a two-column document, for which the smaller font size would
be very useful

[I tried changing /paperfontsize in my Lyx document manually, but that
doesn't work]


Thank you

Philipp
