For example if I did a curl -F 'clbin=@some-image.jpg' https://clbin.com. How do I man curl easily?
How to see manpage of previous command?
bash;command line;zsh
In both bash and zsh (and (t)csh where that feature comes from), provided that history expansion is enabled:man !!:0(admittedly, it's not really shorter than man curl).
