Textedit local links
I cannot find the TextEdit Help page on TextEdit local links. I posted earlier "shortcut to open folder", 8 messy steps. The closest I can find would be "Add clickable links in Textedit on Mac". Apple Care and Automator and Stack Overflow and Finder provide a solid workaround.
Apple Care: search google for (in quotes) "Textedit link to folder".
Stack Overflow: "Mac Textedit link to folder" use the text link format 'file:///Users/myname/Documents/Personal/.../file.rtf'.
Automator: quick action, Workflow receives current 'files or folders' in 'Finder', actions 'Copy to Clipboard'. Save workflow, it saves as service in /Users/username/Library/Services/Copy Path.workflow. Make sure that you save your quick action as "Copy Path".
Finder: putting it all together now, in Finder select the file or folder that you want to open from TextEdit link, right click the target Finder item and select "Copy Path". Type the text that will link to the Finder target, select the text link. Press ⌘K to open link dialogue. Type 'file://' in the link dialog and paste the path that you have copied using your new Finder 'Copy Path' command:
'file:///Users/myname/Documents/Personal/.../file.rtf'
Now we can link to local Finder content in TextEdit with a quick ⌘K copy-paste. Any other TextEdit local link solutions?
