I want to be able to delete the items selected in a view, but am struggling finding a best way to turn the different key presses into a -delete: action that my controller can handle. I think I want (it seems expected functionality anyway) the delete key, the forward delete key, as well as Cmd-Delete to all trigger this action.
The Cocoa Text Bindings system already translates keys and key combinations into invocations of NSResponder methods. <http:// developer.apple.com/documentation/Cocoa/Conceptual/EventOverview/ TextDefaultsBindings/chapter_9_section_1.html>
So, what you need to do is determine which methods those keys are already mapping to, override those methods in the appropriate place in your responder chain (e.g. on your custom view or application delegate), and have them all invoke some common method to do what you want.
Here's a (somewhat dated) third-party page describing the text- binding system: <http://www.hcs.harvard.edu/~jrus/Site/Cocoa%20Text% 20System.html>.
And here's that guy's list of the default bindings, which has a few minor inaccuracies but should be mostly useful: <http:// www.hcs.harvard.edu/~jrus/Site/system-bindings.html>.
The definitive list can be found by interpreting /System/Library/ Frameworks/AppKit.framework/Resources/StandardKeyBinding.dict, but the use of non-printable characters can make interpreting that file somewhat difficult.
