Minor bug *src-5.12.3 should be *src-5.12.5
i've hacked this about and added a TON of skips

EGLFS will drive you insane. You can't quite applications very easily at all (or at all)
Solution - add an escape key handler very high up the stack (top level widget for example)
Alternatively press the "big bomb" icon (which really shouldn't be in production builds)
