MacOS checkmark keybinding

DefaultKeyBinding.dict

// Installation: 
//   1. Save this file as /Users/YOUR_USER_NAME_HERE/Library/KeyBindings/DefaultKeyBinding.dict
//   2. Log out and log back in (or just restart any app where you'd like to use the shortcut)

// What:  Keyboard shortcut to easily insert checkmarks. (Or whatever text you'd like to insert).
//        By default option+v in MacOS inserts a square-root symbol: √
//        I've often used option+v as a quick-and-dirty checkmark. This shortcut lets me get a real checkmark.

{
  // Insert a checkmark with option+v
  "~v" = (insertText:, "✓");
  "~l" = (insertText:, "λ"); // another example, the lambda symbol
}
