Hello Terry. I installed 3.7 from Python.org
First time it crashed,  I was playing around with some basic code (I’m learning), whilst trying to enter [ character (which is option + ^key in spanish keyboard), by mistake I pressed command (key next to option) and crashed IDLE.
Since I saw the crash report, I tried reproducing in in order to report the supposed bug.

Then I restarted IDLE from OSX Spotlight, and successfully crashed it using the same key combo several times.

I did not create any custom keyset, just happened by mistake.

Regards,
