On the L440 and T450 keyboard, for example, there is no Break key. When running a Windows build of Python, Ctrl-C doesn't work, and we must use Break. Thus we need to know how to do that. See [this article on Lenovo.com](https://support.lenovo.com/gb/en/solutions/ht074004-keyboard-shortcut-for-break-pause-scrlk-sysrq-function-on-thinkpad-6-rows-precision-keyboard-thinkpad) and to summarise:
```
Break (FN + B) or (FN + Ctrl + B)
SysRq (FN + S)
ScrLK (FN + K)
Pause (FN + P) or (FN + Alt + P) or (FN + Ctrl + P)
```
