If any other developers are reading, don't rush to incorporate such keybording features. I can name a billion other HI problems I see in Cocoa apps which should be addressed. Things like misuse of file paths (instead of NSDocument which appears to use an FSRef), not setting or using file types, improper use of utility window widgets (Omni, please get a clue), drag+drop pointing to files and not data (Omni, you again), and so much more.
I tend to find Cocoa apps very frustrating. Not least of which is Terminal.app which is the most difficult app to select text in. Maybe I should port Better Telnet, turn it into a Carbon terminal.
