Feature Request: Process kill command + CTRL-C interrupt (EXTRA: Bug report included)

[SMOLKEYS]

As the title pretty much suggests, would it be possible to implement a taskkill and CTRL-C (process interrupt & exit) equivalent in Native mode?

Also, just to add: I'm not sure how to exactly describe this bug I found, but I can specify the steps:

1. Boot into native shell
2. Type any long text (either keyboard-mash or some long coherent string like one two three four five six seven eight nine ten eleven twelve will work)
3. Hit backspace
