Real talk about dem brackets

Real talk about dem brackets

  • Steve Losh's great post A Modern Space Cadet.
    • Shift Parentheses section.
      • You might want to skip the last <autogen> rule, as it makes typing uppercased words by holding the shift key a pretty terrible experience.
    • Control/Escape section.
    • KeyRemap4MacBook is now Karabiner.
  • Using Linux? You can get pretty much the same results with xmodmap, just google around.
  • Shif parentheses can be done in a similar way, I'll post my xmodmap config for them when I get home.
