Can't delete meters on htop with the delete key
I found that on a mac keyboard you could use the Fn+Delete to remove column entries from the setup menu.
My solution was (iterm2 using natural keys) to us Fn+ctrl+delete to remove column entries from the setup menu.
My solution was to delete the htop configuration file using
rm -fv ~/.config/htop/htoprc
While certainly not a true solution, it is a workaround.
