Shabbos 80 – שבת פ

According to Rabanan, even if the object is within three tefachim a minimal hanacha is required.  The Gemara concludes that having the item in one’s hand (which is in transit) is considered sufficient. Why is that regarded as hanacha (see 5b where Rava is unsure whether a nut placed in floating keli is regarded as at rest) ?
