LyX ⇒ Custom Font Size for Presentation

[crismath]

Following sequence (document class beamer):

Document -> Configuration -> Typography -> Base size.

How do I put a size 9pt? Is it just up to 10pt?


Thanks

The base sizes are often 10pt, 11pt, 12pt, but you can enclose things inside \begin{small}...\end{small} or similar (\small, \footnotesize, \scriptsize, and \tiny are also useful here).
