Hidden key command "Play"

I would like to change the key command “play” but I cannot find it in Pref/key command list.

It’s in the Play section of the Key Commands list, and it’s listed like so:

ok this I found but there is nowhere the simple play command that seems hardwired to “space”

It’s this one:

not here

Every single one of the factory keycommands files has “Space” as a default for this. I can’t tell what you’ve added or removed from your own keyboard shortcuts from a screenshot, of course.

thanks Leo
