  // Unbind ctrl-g everywhere.
  // I'm used to hitting it repeatedly in Emacs to cancel things and I expect it to do that consistently everywhere.
  // Unfortutately zed defaults ctrl-g to go to line which I rarely use. Extra unfortunately, this has been difficult to
  // accomplish and I had to bind various things to ctrl-g in various contexts via trial and error to get it to do what
  // I want it to do. I'm sure this is brittle and it certainly is horrible, but it was all that I could come up with
  // right now. The best way to see all the places that I had to muck with this is to search for "ctrl-g". I did bind go
  // to line to "cmd-g cmd-g" like I have in Emacs.
