01 / THE IDEA
What does it mean?
People find it easier to recognize visible choices than retrieve details from memory. Interfaces should keep relevant information accessible.
02 / IN PRACTICE
Make it concrete.
Illustrative example: A recently used address appears as a selectable option instead of requiring someone to type it again.
03 / WHAT TO WATCH FOR
A common mistake.
Hiding essential commands behind memorized shortcuts.
04 / WHEN IT HELPS
When should you use it?
When an interface asks users to remember values or steps from another screen.
