ctrl-click to select multiple elements not working

[ToastBusters]

When paired with jQuery 1.7 the selectable plugin does not allow selecting multiple element by ctrl+clicking, but downgrading jQuery to 1.6 does work. I'm not sure if this is a bug in jQuery UI or in jQuery itself.

The bug is easy to reproduce, simply load up the demo for the selectable plugin using 1.7 instead of 1.6 and ctrl+click will behave like a normal click. I encountered this on both Chrome and Firefox on linux if it makes a difference.

Basically jQuery 1.7 changed the way it assigns event.metaKey, and this broke UI's selectable.

I provide a small fix to overcome this problem (until they fix it in a new version of UI):

$('#selectable').selectable().on('mousedown', '*', function(e){
  if (e.ctrlKey)
    e.metaKey = e.ctrlKey;
});

Selectable: Explicitly check event.ctrlKey now that jQuery differentiates between meta and ctrl. Fixes #7858 - ctrl-click to select multiple elements not working.
