Editorial workflow to simplify the use of hyperlinks in markdown. Uses a combination of the selected region and clipboard to generate the appropriate code. It then puts the cursor in the correct place

	Editorial Macro
	
	Construct a markdown URL string - sensitive to the contents of the clipboard and selected text
	-  Ask whether the clipboard is to be used - you dont know what's in there
	-  check whether it's a URL and react accordingly
	-  if an area is selected and there is also something in the clipboard then the clipboard
	   takes precedence as it's been chosen
