title: How to capture Control+Tab on a NSView keyDown: event?
body: <p>It looks like <code>keyDown:</code> isn't called when Control+Tab is pressed. I've a <code>NSView</code> to render custom widgets, so I need to capture Control+Tab for a custom behavior, but <code>NSApplication sendEvent:</code> <a href="https://developer.apple.com/library/mac/documentation/Cocoa/Conceptual/EventOverview/HandlingKeyEvents/HandlingKeyEvents.html#//apple_ref/doc/uid/10000060i-CH7-SW9" rel="nofollow">captures it to change the next key view</a>. How can I intercept this to get Control+Tab in the <code>keyDown:</code> event?</p>
