Excuse me for my ignorance, but I have just started learning Cocoa/Objective-C and have a question that I can't figure out searching through apple documentation. I have made a very simple web browser, and, as it is now, when the NSTextField for the address loses focus, it loads the address. I only want to address field to perform this action when i hit return/enter. I've played around with the delegates, but can't figure it out. Any help would be appreciated.
