Re-mapping tilde ~ to escape with hidutil, hex code is wrong on technical note?
So i thought I tried 35, but i guess i missed it.  

The `~ key is 35.  

So just to be clear this [technical note] Has everything correct however i was confused by the non-Us keyboard vs graveaccent/Tilde names.

~  key is 35

\| key is 31 and 32 (for us keyboards)
