UNDOCUMENTED LINGO (was:Is it posible to modifiy a sound pitch?)

[Richard]

Hi,

I just read the message below which was about some hidden feature (pitching
sound in Director) that I never knew of. This is not the first time I
encountered handy lingo that wasn't documented and that remained hidden in
Director(probably since it's experimental lingo and might not work
everywhere). Does anyone know of an online website/archive where one can
find undocumented lingo + examples?

Thanks

Richard

command is undocumented as far as I know, and I dont know exactly how to
find it. The only instance I've found of it is in the Message window's
commands list. Any tip for using it?
