This is particularly useful if you are planning to copy the whole string to the shell to run a command. Quotes can be toggled at runtime using <kbd>^T</kbd>.
Note that the filename is not escaped. So copying may still fail for filenames having quote(s) in them.
#### copy file paths when X is missing
A very common scenario on headless remote servers connected via SSH. As the clipboard is missing, `nnn` copies the path names to the tmp file `/tmp/nnncp$USER`.
