What does this kanji mean?

Question:

I would like to know what the (手) is supposed to mean in あでゅ(手)

"Adieu *waves goodbye*"

I'm guessing?

I can't be 100% sure considering I don't know much about Japanese texting and such.

Did I translate accurately?

Answer:

手 means hand.

In this case, 手 means "waving hands" because he's trying to say goodbye. But this is not common.
