handling keyboard shortcuts with jQuery

jwerty is a JS lib which allows you to bind, fire and assert key combination strings against elements and events. It normalises the poor std api into something easy to use and clear.

jwerty is a small library, weighing in at around 1.5kb bytes minified and gzipped (~3kb minified). jwerty has no dependencies, but is compatible with jQuery, Zepto or Ender if you include those packages alongside it.

How to use

Use `jwerty.key` to bind your callback to a key combo (global shortcuts)

jwerty.key('ctrl+shift+P', function () { [...] });
jwerty.key('⌃+⇧+P', function () { [...] });

Specify optional keys...

jwerty.key('⌃+⇧+P/⌘+⇧+P', function () { [...] });

or key sequences...

jwerty.key('↑,↑,↓,↓,←,→,←,→,B,A,↩', function () { [...] });

or regex-like key ranges.

jwerty.key('ctrl+[0-9]', function () { [...] });

or a mixture!

jwerty.key('ctrl+[0-9],f/h', function () { [...] });

Pass in a context to bind your callback:

jwerty.key('⌃+⇧+P/⌘+⇧+P', function () { [...] }, this);

Pass in a selector to bind a shortcut local to that element

jwerty.key('⌃+⇧+P/⌘+⇧+P', function () { [...] }, this, '#myinput');

Pass in a selector's context, similar to jQuery's $('selector', 'scope')

jwerty.key('⌃+⇧+P/⌘+⇧+P', function () { [...] }, this, 'input.email', '#myForm');

If you're bining to a selector, you can also ommit the function context:

jwerty.key('⌃+⇧+P/⌘+⇧+P', function () { [...] }, 'input.email', '#myForm');

Use `jwerty.event` as a decorator, to bind events your own way:

$('#myinput').bind('keydown',  .event('⌃+⇧+P/⌘+⇧+P', function () { [...] }));

Use `jwerty.is` to check a keyCombo against a keyboard event:

function (event) {
    if ( jwerty.is('⌃+⇧+P', event) ) {
        [...]
    }
}

Or use `jwerty.fire` to send keyboard events to other places:

jwerty.fire('enter', 'input:first-child', '#myForm');
