# jQuery.Hotkeys [![Build Status](https://secure.travis-ci.org/jeresig/jquery.hotkeys.png)](http://travis-ci.org/jeresig/jquery.hotkeys)

#About
**jQuery Hotkeys** is a plug-in that lets you easily add and remove handlers for keyboard events anywhere in your code supporting almost any key combination.

This plugin is based off of the plugin by Tzury Bar Yochay: [jQuery.hotkeys](https://github.com/tzuryby/jquery.hotkeys)

The syntax is as follows:

```javascript
$(expression).bind(types, keys, handler);
$(expression).unbind(types, handler);

$(document).bind('keydown', 'ctrl+a', fn);

// e.g. replace '$' sign with 'EUR'
$('input.foo').bind('keyup', '$', function(){
  this.value = this.value.replace('$', 'EUR');
});
```

Syntax when wanting to use jQuery's `on()`/`off` methods:

```javascript
$(expression).on(types, null, keys, handler);
$(expression).off(types, handler);

$(document).on('keydown', null, 'ctrl+a', fn);

// e.g. replace '$' sign with 'EUR'
$('input.foo').on('keyup', null, '$', function(){
  this.value = this.value.replace('$', 'EUR');
});     
```

## Example

[Example](https://rawgit.com/jeresig/jquery.hotkeys/master/test-static-01.html)

## Event Types

Supported types are `'keydown'`, `'keyup'` and `'keypress'`

## jQuery Compatibility

Works with jQuery 1.4.2 and newer.

It is known to be working with all the major browsers on all available platforms (Win/Mac/Linux)

 * IE 6/7/8+
 * FF 1.5/2/3+
 * Opera-9+
 * Safari-3+
 * Chrome-0.2+

## Browserify Compatibility
If you want to include this module in a Browserified project, just add it to node_modules and require it.
```javascript
require('jquery.javascript');
```

This will work if jQuery is global (ex. served from a CDN). If it's not, you need to (shim it)[https://github.com/thlorenz/browserify-shim#a-expose-global-variables-via-global]:
```javascript
{
  "browserify-shim": {
    "jquery": "global:jQuery"
  }
}
```

## Notes

Modifiers are not case sensitive (`Ctrl` == `ctrl` == `cTRL`)

If you want to use more than one modifier (e.g. `alt+ctrl+z`) you should define them by an alphabetical order e.g. alt+ctrl+shift

Hotkeys aren't tracked if you're inside of an input element (unless you explicitly bind the hotkey directly to the input). This helps to avoid conflict with normal user typing.

You can use namespacing by adding a suffix to the event type (e.g. `keyup.toggle`)


### Meta and Hyper Keys
Meta and hyper keys don't register on `keyup` in any browser tested.

#### Chrome 33.0.1750.117
Meta key registers on `keydown` event.
Hyper key registers on `keydown` event.

#### Firefox 27.0.1 and Safari 7.0.1
Meta key registers on `keydown` and `keypress` events.
Hyper key registers on `keydown` and `keypress` events.

#### Opera 19.0
Meta key doesn't register at all :(
Hyper key registers on `keydown` and `keypress` events.

#### TL;DR
Bind to `keydown` event for meta and hyper keys, but meta key does not work in Opera ;)

### Addendum

Firefox is the most liberal one in the manner of letting you capture all short-cuts even those that are built-in in the browser such as `Ctrl-t` for new tab, or `Ctrl-a` for selecting all text. You can always bubble them up to the browser by returning `true` in your handler.

Others, (IE) either let you handle built-in short-cuts, but will add their functionality after your code has executed. Or (Opera/Safari) will *not* pass those events to the DOM at all.

*So, if you bind `Ctrl-Q` or `Alt-F4` and your Safari/Opera window is closed don't be surprised.*
