Command+Option+V: So many options

Did a copy/paste and accidentally stumbled onto the option enhancer that I had not remembered using befor

Example: Command+C

Start with a simple command+c operation copy command I do all the time, but now in the paste target press Command+Option+V and you get in my case was selecting a file path this

So many options I did not know about, the substitution seems really appealing along with the replace regular expression.  How did I miss this for so long?
