JavaScript Shortcuts Library

JavaScript Shortcuts Library (jQuery plugin)

Usage

Add a shortcut:

$.Shortcuts.add({
    type: 'down',
    mask: 'Ctrl+A',
    handler: function() {
        debug('Ctrl+A');
    }
});

Start reacting to shortcuts:

$.Shortcuts.start();

Add a shortcut to “another” list:

$.Shortcuts.add({
    type: 'hold',
    mask: 'Shift+Up',
    handler: function() {
        debug('Shift+Up');
    },
    list: 'another'
});

Activate “another” list:

$.Shortcuts.start('another');

Remove a shortcut:

$.Shortcuts.remove({
    type: 'hold',
    mask: 'Shift+Up',
    list: 'another'
});

Stop (unbind event handlers):

$.Shortcuts.stop();

Features

Multiple key combinations and multiple lists:

$.Shortcuts.add({
    type: 'hold',
    mask: 'Shift+Up,Shift+Down',
    handler: function() {
        doSomething();
    },
    list: 'first,second'
});

Chaining:

$.Shortcuts.add({
    type: 'down',
    mask: 'Ctrl+A',
    handler: function() {
        debug('Ctrl+A');
    }
}).start();

Enable/disable shortcuts in input fields and textareas:

$.Shortcuts.add({
    type: 'down',
    mask: 'Ctrl+S',
    enableInInput: true,
    handler: function() {
        debug('Ctrl+S');
    }
});
