Re: Converting keyCode&modifierFlags to NSString

If there is a method for this specific case, I'm not aware of it, but 
it wouldn't be hard to add a category to NSEvent to do what you're 
looking for.

It's possible that the actions you want to perform actually belong 
elsewhere. For instance, pressing the delete key usually implies you 
want to delete something (ORLY!), and if you're working on a custom 
NSView subclass, the method to implement would be -(IBAction)delete: 
(id)sender, which by virtue of being implemented would automagically 
enable a Delete menu item in the Edit menu, etc. etc. The same for -
scrollUp:, -scrollDown:, and a number of other methods declared (but 
not implemented by default) for NSResponder and NSView.
