You can either click or press any keys, or both if you want.

Alt-F4 or Cmd-Q to quit. Or just don't close it.

You can do hey & to just leave it open.

If this doesn't work for you, you may need to update Node. (On Linux or Mac, try npm i -g n && n latest).

If it still doesn't work, please open an issue and I'll try to fix it ASAP!
