`nnn` can invoke plugins in the current directory (`$PWD` for the plugin) with the currently selected file name as the argument.
Copy the plugins of your interest from the [plugins](https://github.com/jarun/nnn/tree/master/plugins) directory and let `nnn` know the location:

Use the pick plugin shortcut to visit the plugin directory and pick a plugin. Repeating the same shortcut cancels the operation and puts you back in the original directory.
Use the pick plugin shortcut to visit the plugin directory and execute a plugin. Repeating the same shortcut cancels the operation and puts you back in the original directory.

Plugins can access:
- all files in the directory (`nnn` switches to the dir where the plugin is to be run so the dir is `$PWD` for the plugin)
- the currently highlighted file (the file name is passed as the argument to a plugin)
- the current selection (by reading the file .nnncp, see the plugin `ndiff`)
- the current selection (by reading the file `~/.config/nnn/.selection`, see the plugin `ndiff`)
Each script has a _Description_ section which provides more details on what the script does, if applicable.
