--- Comment #7 from Mark K markk@clara.co.uk --- WinUAE has keyboard logging which you can enable by running it with -log -inputlog 1 arguments.
Doing that, on Windows 10 there is this output when pressing Pause with emulation running: HANDLE=1003d CODE=1d Flags=4 VK=13 MSG=100 EXTRA=0 SC=1d HANDLE=1003d CODE=45 Flags=0 VK=ff MSG=100 EXTRA=0 SC=45 HANDLE=1003d CODE=1d Flags=5 VK=13 MSG=101 EXTRA=0 SC=1d HANDLE=1003d CODE=45 Flags=1 VK=ff MSG=101 EXTRA=0 SC=45
However under Wine, this is the output when pressing Pause: HANDLE=2 CODE=45 Flags=0 VK=13 MSG=100 EXTRA=0 SC=45 HANDLE=2 CODE=45 Flags=1 VK=13 MSG=101 EXTRA=0 SC=45
