Numpad-based Keypad Navigation for Gen 3 Systems
Credit due to one of our avid users, @worthing and Redditor u/Hannover92 for this one:
A way to navigate the SimpliSafe Gen 3 Keypad Menu without having the read the screen or use the arrows, by instead pressing a sequence of numbers to get to the right options.
Current and previous owners of the Original SimpliSafe might remember that this was actually already a feature of that generation's Keypad. For example, to get to Test Mode, one would press the button sequence:
Press [Menu] > Type in Master PIN > Press  > Press [Menu] to exit
