direct exposure of just an item's URL

[kinook]

To insert an internal link to another item within a UR item's text, you don't need to use 'Copy with URL' -- you can just use a regular copy.

'Copy with URL' does more than a regular copy -- it also copies the item's title and its URL attribute (if it is has a URL attribute) as text for pasting into other applications, but I now realize that's not what you were trying to do.

Copying the URL of the UR item itself (regardless of what type of item it is) for linking to the UR item from other applications is accomplished as $bill indicated, via Item | Copy Item Command-Line.
