Is there a name for this respectful hand-wave?

I recently attended a language workshop where not a word of English was spoken -- everything was in the foreign language, and our tutor would do funny little mimes to indicate meanings of phrases, etc.

One of the things he did was to illustrate the differences when saying "you" (formal) to a superior person and when saying "you" to a friend. To show that he was addressing a person to whom we should use the former, he bowed low with one leg extended and with his left hand made a series of waves such as the British Royal family use when waving to crowds -- almost circular waves from the wrist, if you know what I mean.

It got me wondering -- it's a gesture familiar from pantomime and the like when a courtier or commoner is addressing the Sultan -- but does it have a name? I mean the hand-wave, but specifically this one, which would be given with a low bow and one leg extended.

Would be very grateful if anyone can help! Thanks.
