How To Cancel Send Commands?

I know you can do \\lua unload send to stop send. The problem is I have several send commands that is binded to the F1 key on my keyboard and I want to stop it whenever. If I unload send, it does stop send but when I load send again, it continues the remaining send commands (did not press the F1 key). In other words, is there a way to stop/cancel/reset send? My only fix at the the moment is completely shutdown Windower (logging out and logging back in does not work).

What exactly is your F1 bind doing?
