What this calculator does

Before touchscreen keyboards, feature phones used “multi-tap” T9 text entry: each number key represented several letters, and you pressed the key repeatedly to cycle through them (press 4 once for G, twice for H, three times for I).

The keypad layout

This uses the classic keypad mapping: 2=ABC, 3=DEF, 4=GHI, 5=JKL, 6=MNO, 7=PQRS, 8=TUV, 9=WXYZ, 0=space, and 1=period. For each key press you select, choose the number key and which tap (1st, 2nd, 3rd, or 4th letter on that key) to decode the intended letter.

This demonstrates the deterministic multi-tap method; the smarter predictive “T9” dictionary lookup (which guessed whole words from a single tap per letter) additionally required a word dictionary and is not reproduced here.
