With this, plugin `fzy-open` can be run with the keybind <kbd>:o</kbd>, `mocplay` can be run with <kbd>:p</kbd> and so on... The key vs. plugin pairs are shown in the help and config screen. Up to 10 plugins can have such keybinds.
To assign keys to arbitrary commands (non-shell interpreted) and invoke like plugins, add `_` (underscore) before the command. For example:
export NNN_PLUG='x:_chmod +x;o:fzy-open'
**Method 2:** 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.
## Create your own plugins
