Thanks for the info Batista, none of those links helped get past the next hurdle, I do already have copy folder path/name in my context menu, added it previously but that's unrelated to this current need.
Using argument https://www.google.com/search?q="%1" gets me the full Filename + folder path/file adrress + extension into the subsequent Chrome search. Essentially the string "%1" is getting that, proof of concept yay, I now just need the string term to only insert the filename on it's own with no extension, even with extension would still be very useable.
