Another way some follower posted:
"left pointing arrow key?
That's the delete key, IIRC, fn + that key works as supr."
Other:
"map caps lock into a right arrow key + backspace macro."
tried it does not work, I googled the options you mentioned before. On a mac the backspace functions as the delete key.
Then we will have to fix that for the next update.
sounds good!
