[[Keyboard Maestro] How to convert the clipboard (a markdown link) to simple text format 2023-11-26 07:20 Vito <kmforum@forum.keyboardmaestro.com>](message://%3Cdiscourse/post/165046@forum.keyboardmaestro.com%3E)
It checks to see if the current clipboard starts with [[, and if so, applies a regular expression to chop out all the bits you don't want, leaving just the part you do, and putting that back on the clipboard. The demo macro doesn't have a trigger of any sort, so to test it, just make sure a markdown link is the top item in the clipboard, then run it manually.
It works here in testing, though I only used the one sample string you provided. If there are other Markdown link formats, I'm not sure if my expression would capture them all or not. (I don't use or know much of anything about Markdown, short of using it here in posts in very simple ways.)
