I like this idea.  I never use the "reading punctuation" setting at all.
I keep it synchronized with the Speakup punctuation level,
so I have to enter two commands to change my punctuation setting.
I think it would be more useful to be able to control the synthesizer's
level from the keyboard, for those synthesizers which can benefit from it.
