This is where I got to (with broken code)

Spoiler:

Something like.... Which is broken.. I will figure out what I did tomorrow.

stupid cut and paste loop error. will pick this up tomorrow.
noted here for the morning.

I will check the matching brackets when I am less tired.

But this is close...
I get the relevant output... mainly...

ev.code = <435>
ev.code = <435>
ev.code = <435>
ev.code = <435>
Exiting.
ev.code = <161956>
