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.
  • Caps Lock as Control/Escape.
• Shif parentheses can be done in a similar way, I'll post my xmodmap config for them when I get home.
