You cannot expect people to do a full code review for you on Stack Overflow. This platform is for specific questions or specific problems you encounter. If you need help using Keyevents, explain specifically what you want to accomplish with Keyevents (for example: I tried to open a new window) , what you tried to do (I entered these lines of code...) and what happened that caused you to seek help (instead of a window, the program crashed with this error message...). — Tomer 30 secs ago

Okay, I think I have a handle on this question: Is it that this class's single responsibility is to route actions to the appropriate processors based on conditions? If so, it appears that you do have working code, and in general requests for improvement on working code should go on Code Review (of course, review their On-Topic rules). I have an idea, and feel free to post over there and tag me. — chrylis -cautiouslyoptimistic- 25 secs ago

@AmitDash Lets say original state of branch has commit head dcf81dff my-commit-message. Code review is made and the pull request is declined. A developer now makes updates to that feature branch and then rebase squashes those updates. The commit head now would change to 2654c804 my commit-message.
