flash actionscript: I have an .as file with this code within it
so when the send_pb button is pushed then onSendMessage causes the message to
be sent.....I'd like the enter key on the keyboard to do the same thing. I
tried various ways to do it within the .as file but nothing seems to work.

// Delegate the click event from send_pb to onSendMessage

send_pb.addEventListener("click", Delegate.create(this,onSendMessage));

Hi,
Just try to add the listener Object for the KeyBoard
And in the KeyPress Enter, you just check out the Focus,
if it is in the target movieclip , you just call the same function what you
have in the button on Release......function....
