Hi and thanks for opening this PR! 


The code looks ok, there are a few things to be adjusted before merging:

• Could you add your press in tests/default_presses.py
• Could you update the README with a short description of the press
• Could you please run make style to make sure the format is ok
• I left some comments in the review, concerning minor code changes for readability

[JoelSeniorLiang]
