Hello Crabman and thank you for the comment!
It's currently not possible to customize keyboard shortcuts but it's definitely a great idea. At the same time, the absence of any emulator / compiler should prevent an unhandled error from arising, so it will definitely be handled in the next release, as well. Moreover, the next version will also have more features and an additional target, so surely it will be useful to have this change you suggested.
Thank you again, and happy retrocoding!
