Abstract
A single press method for entering text using a keypad is disclosed. A conventional four-row by three-column 12-key keypad is used to enter all of the letters of the alphabet using single key actuation. Depending on the letter, either a single key or multiple side-by-side keys, such as a pair of side-by-side keys, that can be substantially simultaneously depressed by a user's finger or thumb are used to enter alphabet letters.
