Comment 11 for bug 597825

Finally! After an hour or so of searching various sources, including the lovely
MSDN site, I something (anything) on how to retrieve this setting. Oddly
enough, it's in the form of a message and not a function or registry setting.
But there must be an underlying registry setting somewhere.

The message is WM_QUERYUISTATE although I'm not sure what window you'd send that
message to. When you think about it, you could probably send it to the
top-level Mozilla window, because it would inherit the default Windows settings
and would never change that setting.

(It's good to see that Microsoft has absolutely no naming conventions anymore,
and that their names are distinct and concise.)

Another question about this setting, for someone with W2K to answer. Does this
apply only to menus or also to accelerators on buttons, fields, etc?
