Fairly sure /r IS /reply. The problem presented by the OP was when one is typing a long reply that starts with /r in order to reply, only to get a gil spam message before the message is sent, and thus the message being sent to the gilseller rather than the intended character. The reply command processes when the message is sent, so anyone sending you tells while you're typing will become the new recipient.

Of course, the hotkey is the most effective solution, so... All's well that ends well.
