Did some rooting around. YouTube is using this
http://s.ytimg.com/yt/swf/subtitle_module-vfl99400.swf which I opened in
Flash CS4 and poked around in the debugger. I don't know much about Flash,
but I did not see any overt declaration of base caption/subtitle size.
Perhaps someone who knows more can find it.

The keyboard shortcuts are documented here:
http://www.youtube.com/t/captions_about

This is quotable: "While you can choose a caption track in the sub-menu, you
can also control captions with various keyboard short-cuts." Its true you
can control the size (with + and -) and background (with B) of the caption
text, but as far as I can tell Jim there's no keyboard shortcut for toggling
the captions off/on. The caption icon doesn't receive tab focus in either
IE7 or IE8.

Re-reading my original post, I see that I didn't really express that as a
question, but there is one in there. I'm wondering: How did the folks at
YouTube attain such a large default font on their captioned video?

Thanks,
Terrill
