Copy to clipboard (include paths): Ctrl+Alt+C
Or for those poor mouse-bound souls: Right-click > File Names > ...
Ahh.. so, that's where it is hidden..
I must say, 'File Names' is quite an obscure title for that.
IMO, it should be 'Copy to Clipboard..' instead of 'File Names' and the sub-menu labels should be:
-- File/Folder Name
-- Full Path
-- URL
and 'Insert to Command Line' is IMO superfluous: the 3 sub-menus are sufficient; I can easily handle that with 'Paste' or Ctrl+V.
Plus, it doesn't cover 'Insert Full Path into Command Line', 'Insert URL into Command Line' anyway.
