Several Hook users have written forum & blog posts about using Hook with Keyboard Maestro.
Here’s a Keyboard Maestro action by Kourosh Dini, of Being Productive, for copying a link to the foreground item, in which Keyboard Maestro invokes Hook: One keystroke faster with Hook | Being Productive. That means you can use a shortcut to skip the Hook window, and copy a link to the current item.

ComplexPoint has also posted a Keyboard Maestro macro for Copy Markdown Link here: Copy as (Hook) Markdown link – Macro Library – Keyboard Maestro Discourse
