# Copy Special Character

![](/files/-MdrheMligah4ddSbWk_)

This command illustrates an [interactive List](/reference/command-response-view-list.md), as well as using **Tab** to navigate to another location within the command.

In this case, hitting **Enter** on an Option will copy the special character, while hitting **Tab** will show another view letting someone choose to copy the hex value instead.

```javascript
/*
 * A command that shows special characters. Hitting Enter
 * will copy character, hitting Tab will give other ways
 * to copy the character: HTML hex code, for example.
 */

/**
 * Gets arguments passed in to script, like: --character=control
 * and stores it into an array, like: args['character'] = "control".
 */
const args = process.argv.slice(2).reduce((agg, arg) => {
  const match = arg.match(/^--(?<key>\w+)=(?<value>.+)$/);
  return match ? { ...agg, [match.groups.key]: match.groups.value } : agg;
}, {});

let response;
if (args["character"]) {
  response = showOptionsForCharacter(args["character"]);
} else {
  response = showAllCharacters();
}
console.log(JSON.stringify(response));

/*
 * The view that is shown when someone runs the command.
