keymaster.js is a simple (<50 LoC) micro-library for defining and dispatching keyboard shortcuts. It has no dependencies.

It's a work in progress, so spare me your nerdrage but instead contribute! Patches are welcome, but they are not guaranteed to make it in.

Two global methods are exposed, key for defining shortcuts, and keyScope for switching scope.

See test.html for a live demo.

  key('c', 'issues', function(){
    console.log('c/issues');
  });
    
  key('i', function(){
    keyScope('issues');
    console.log('Switched to "issues" scope.');
  });
  
  key('i', function(){
    console.log('(example of multiple assignment)');
  });
  
  key('o, enter, left', function(){
    console.log('o, enter or left pressed!');
  });

  key('ctrl+c', function(){
    console.log('this is not the command line');
  });

  key('⌘+right,shift+left,ctrl+shift+alt+d', function(event){
    console.log('command+right, or shift+left, or ctrl+shift+alt+d');
    event.preventDefault();
  });

TODOs:

• Make it work on IE (7+)
• Add a way to easily cancel propagation/default behavior
• Make behavior with INPUT/SELECT/TEXTAREA configurable
• Comprehensive test suite
