User Keys RPN

[luisphysics]

So I'm trying to shortcut the CONVERT() in RPN to make my life easier. I my program is easy

KEY K_Eex()
BEGIN
RETURN "CONVERT()";
END;

but when I use the user key in RPN it just prints the convert then I have to press OMG [ENTER] all over again. This makes me grumpy. Does anyone know how I can just tell it to press enter for me and trust me that I'll use it where I will need it?

I was thinking it should look like this

KEY K_Eex()
BEGIN
RETURN "CONVERT()";
// Some code here that presses enter for me
END;
