@cvp Thank you, so much. It works! Now to study your changes. ;-)

I’m curious to know if Pythonista for iOS supports Seth Brown’s python script within the “md - flip links” workflow, posted at:

https://brettterpstra.com/projects/markdown-service-tools/#linksfliplinkstyle

I copied the python script out of the macOS workflow, saved it within Pythonista, and enabled it as a share extension shortcut. When I select the markdown text in iAWriter and launch the shortcut, nothing happens. What other tweaks do I need to make?

Thanks!

Here’s the code:
