Body
It can be done by using IOKit and the HIDManager class. If exclusive access to the keyboard is desired, the <code>kIOHIDOptionsTypeSeizeDevice</code> option can be used, but the program will have to be run with root privileges. A stub of the code required to obtain this result is shown below: <pre><code>// Create a manager instance IOHIDManagerRef manager = IOHIDManagerCreate(kCFAllocatorDefault, kIOHIDManagerOptionNone); if (CFGetTypeID(manager) != IOHIDManagerGetTypeID()) { exit(1); } // Setup device filtering using IOHIDManagerSetDeviceMatching //matchingdict = ... IOHIDManagerSetDeviceMatching(manager, matchingdict); // Setup callbacks IOHIDManagerRegisterDeviceMatchingCallback(manager, Handle_DeviceMatchingCallback, null); IOHIDManagerRegisterDeviceRemovalCallback(manager, Handle_RemovalCallback, null); IOHIDManagerRegisterInputValueCallback(manager, Handle_InputCallback, null); // Open the manager and schedule it with the run loop IOHIDManagerOpen(manager, kIOHIDOptionsTypeSeizeDevice); IOHIDManagerScheduleWithRunLoop(manager, CFRunLoopGetCurrent(), kCFRunLoopDefaultMode); // Start the run loop //... </code></pre> More detailed information can be found in the Apple docs over here: <a href="http://developer.apple.com/library/mac/#documentation/DeviceDrivers/Conceptual/HID/new_api_10_5/tn2187.html" rel="noreferrer">http://developer.apple.com/library/mac/#documentation/DeviceDrivers/Conceptual/HID/new_api_10_5/tn2187.html</a> The complete code I used for my application can be found here: <a href="https://gist.github.com/3783042" rel="noreferrer">https://gist.github.com/3783042</a>

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
