Thanks for your reporting. F2 mode is currently under development in the master branch. So, the key binding won't work (for now). I'll update this when next version is released ❤️

This issue is fixed via #28. The code is already in master. You can check it out. I'm batching the code, and do final tests before a new release 😃
