I think my most used script when writing blog posts is ‘Safari Tabs to Markdown References List’ which adapts an old Brett Terpstra script that collects all the URLs and titles of the active Safari window and inserts them into BBEdit as a Markdown reference list. This particular version uses a feature from BBEdit’s Clippings that allows you to press tab to cycle through the reference list to set its identifier.

I’ve had it for yonks, but after a little digging I think I found the definitive source: http://ranea.org/bbedit-markdown.html
