- navigate to another file in the same directory to select a range of files
- press <kbd>^Y</kbd> (or <kbd>Y</kbd>) _again_ to copy the paths and exit the selection mode
The files in the list can now be copied (<kbd>P</kbd>), moved (<kbd>V</kbd>) or removed (<kbd>X</kbd>).

File paths are copied to the temporary file `DIR/.nnncp`, where `DIR` (by priority) is:

To use the copied paths from the cmdline, use command substitution. For example, if `DIR` above is `/home/user`:
# bash/zsh
ls -ltr `cat /home/user/.nnncp`
ls -ltr $(cat /home/user/.nnncp)
# fish
ls -ltr (cat /home/user/.nnncp)
An alias may be handy, e.g. when you want to copy selection at the _run a command_ prompt:
alias ncp='cat /home/user/.nnncp'
so you can easily handle files together:
# bash/zsh
ls -ltr `ncp`
ls -ltr $(ncp)
# fish
ls -ltr (ncp)

Along with default copy, `nnn` can pipe the absolute path of the current file or multiple files to a copier script. For example, you can use `xsel` on Linux or `pbcopy` on macOS.

##### get selection manually ##### get selection manually
To get a space-separated list of the file paths in selection, say at the command-prompt: NOTE: In the following examples we assume the copy file is at `~/.nnncp`.
The file paths are `NUL`-terminated, so additional processing is required to make them usable.
To get a space-separated list of the file paths in selection:
cat ~/.nnncp | xargs -0 echo cat ~/.nnncp | xargs -0 echo
Set an easy to remember alias: To get a newline-separated list of the file paths in selection:
alias ncp="cat ~/.nnncp | xargs -0 echo" # bash/zsh
ls -ltr `cat /home/user/.nnncp | tr '\0' '\n'`
ls -ltr $(cat /home/user/.nnncp | tr '\0' '\n')
