A cool link manipulating feature you probably didn’t know about : Focus on Copied Link ⌃⇧⌘L. We introduced it earlier this year but had not documented it.
In a nutshell: if you’ve copied a link from any app (including Hook), you can focus Hook onto it. Then you can use all of Hook’s features on it. If you copy it again, for instance, you’ll get multiple representations of the link. You can easily get a Markdown version of the link too, by doing
Copy Markdown Link from there.
So, Hook amongst other things contains a huge set of link manipulation and navigation features..
