The keypad pattern
Patterns last longer than details
Twelve buttons on a keypad. So many combinations. Each one has its own pattern.
Codes open gates and devices. Dates mark the milestones.
The numbers are important. Hard to recall when learning. The fingers find them.
123 is a line across the top. 1937 is an X or the corners. The double tap on the same button. All movements on the keypad.
A map route works the same way. Forget the street names and the outline takes over.
The pattern uncovers the details.
