Arrow from top arrow to bottom arrow












3















Consider:



documentclass[14pt,reqno,a4paper]{amsart}
usepackage{extsizes}
usepackage{blindtext}
textheight 9.3in textwidth 6.5in
calclayout
usepackage{amsmath,amsthm,amsfonts,amssymb}
usepackage{hyperref}
usepackage{mathrsfs}
usepackage[all]{xy}
usepackage[normalem]{ulem}
usepackage{tikz-cd}
usepackage[utf8]{inputenc}
usepackage[english]{babel}

usepackage{color}
pagestyle{myheadings}
begin{document}
begin{tikzcd}
(mathcal{C}/U)^{text{op}} arrow[rrr, "{underline{text{Mor}_{mathcal{F}}}(x,y)}", bend left=49] arrow[rrr, "{underline{text{Mor}_{mathcal{G}}}(Psi(x),Psi(y))}"', bend right=49] & & & (text{Set})
end{tikzcd}
end{document}


The above code results in the following diagram:



Enter image description here



I want to add an arrow from the above arrow to the below arrow.



How do I add that arrow? What more can be done in the code that I have written rather than writing totally different code?

            @PraphullaKoushik You can even shorten a bit the Rightarrow, if you prefer, with shorten=<dimension>, for example, shorten=2pt.

            newcommand{uMor}[1]{operatorname{underline{Mor_{#1}}}}. Shortening the vertical arrow is definitely needed.
