KeyFunctions lets you respring, reboot, or invoke safe mode with text-based commands

Because of how frequently I handle jailbreak tweaks on my jailbroken iPhone, I respring my device constantly. While some tweaks have respring buttons baked right into them for convenience, I've found that having a backup method for respringing or invoking Safe Mode on your handset can be particularly advantageous.

A whole host of tweaks in Cydia can help you respring your device in various ways, but one of the latest releases called KeyFunctions by iOS developer AlexK piqued my interest.
