<!-- ng-class style -->
<button class="btn btn-default" ng-keypress="{enter: doStuff, up-arrow: doStuff2}">Activate Me!</button>

<!-- dual attribtues -->
<button class="btn-default" ng-keypress="doStuff" key="up-arrow">Activate Me!</button>

@whitelynx Here's my thoughts on the api for a keypress directive.

My issue with the first one is that you actually can't parse that as normal JS; since you have "doStuff()" and "doStuff2()", those would both get executed as soon as the attribute is parsed. Instead, they'd have to either be strings (that we'd run through eval) or function definitions.

Oh, my bad. That's a typo.

See, Angular has support for this; this is exactly what they do in the ng-class directive. So, I believe $parse is what we'd be looking for... but we can check the code of ng-class.
