Abstract
Multiple touch entries on an input device are recognized. Upon a user selecting a first key, the first key is recognized based on first detected values. The first detected values are mapped to the first key based on a first mapping of detected values to keys. When the first key supports at least one secondary key, upon a user selecting a second key while continuing to select the first key, the second key is recognized based on second detected values. The second detected values are mapped to the second key based on a second mapping of detected values to keys. The second mapping of detected values to keys is different than the first mapping of detected values to keys.
