For programming you only need to connect VDD, GND, SWDIO and SWCLK, see the debug IN header on the DK:

You can connect a button between the SWDIO/nRESET pin and GND for manual reset.

I'll add that once the debug interface has been used to flash firmware or debug an application, but IC must first be fully power cycled before the Reset line will work again.

Thank you for your comment. You can also do this with the debugger as stated in chapter 11.1.3 "Resuming normal mode" in the Reference Manual. This can be done with the command "nrfjprog --pinreset". I did not find out how you can do this in keil.
