Wrong direction. OP wants to open Ghostty from a Finder window, not vice versa.

I think they are looking for the opposite: open a Ghostty window from Finder.

Yeah, exactly, like Ctrl+Alt+T opening Xterm in Ubuntu. If I am not mistaken, if you have a file explorer open it will automatically open terminal in that specific folder(i.e. kind of like `cd`ing there first)
