Question

In Mac OS / Cocoa, may I synthesize keyboard entries - strings - for the frontmost application in a transparent way?

Sure, you'll want to use CGEventCreateKeyboardEvent to create keyboard events, then post them as such:

    CGEventRef keyup, keydown;
    keydown = CGEventCreateKeyboardEvent (NULL, (CGKeyCode)56, true);
    keyup = CGEventCreateKeyboardEvent (NULL, (CGKeyCode)56, false);

    CGEventPost(kCGHIDEventTap, keydown);
    CGEventPost(kCGHIDEventTap, keyup);
    CFRelease(keydown);
    CFRelease(keyup);

It's a bit more complicated than AppleScript but it does the trick. You do have to explicitly post a keydown and then a keyup event. More information at the Quartz Event Services Reference.
