Cocoa Keyboard Shortcuts in Dialog without an Edit Menu

Improving on that CocoaRocket solution:

The following saves having to subclass NSTextField and remembering to use the subclass throughout your application; it will also enable copy, paste and friends for other responders that handle them, eg. NSTextView.

Put this in a subclass of NSApplication and alter the principal class in your Info.plist accordingly.

- (void) sendEvent:(NSEvent *)event {
    if ([event type] == NSKeyDown) {
        if (([event modifierFlags] & NSDeviceIndependentModifierFlagsMask) == NSCommandKeyMask) {
            if ([[event charactersIgnoringModifiers] isEqualToString:@"x"]) {
                if ([self sendAction:@selector(cut:) to:nil from:self])
                    return;
            }
            else if ([[event charactersIgnoringModifiers] isEqualToString:@"c"]) {
                if ([self sendAction:@selector(copy:) to:nil from:self])
                    return;
            }
            else if ([[event charactersIgnoringModifiers] isEqualToString:@"v"]) {
                if ([self sendAction:@selector(paste:) to:nil from:self])
                    return;
            }
            else if ([[event charactersIgnoringModifiers] isEqualToString:@"z"]) {
                if ([self sendAction:@selector(undo:) to:nil from:self])
                    return;
            }
            else if ([[event charactersIgnoringModifiers] isEqualToString:@"a"]) {
                if ([self sendAction:@selector(selectAll:) to:nil from:self])
                    return;
            }
        }
        else if (([event modifierFlags] & NSDeviceIndependentModifierFlagsMask) == (NSCommandKeyMask | NSShiftKeyMask)) {
            if ([[event charactersIgnoringModifiers] isEqualToString:@"Z"]) {
                if ([self sendAction:@selector(redo:) to:nil from:self])
                    return;
            }
        }
    }
    [super sendEvent:event];
}

// Blank Selectors to silence Xcode warnings: 'Undeclared selector undo:/redo:'
- (IBAction)undo:(id)sender {}
- (IBAction)redo:(id)sender {}
