Here’s an example of how the Activity Row can be used to expand the vocabulary available. When the MASKS key is chosen, the word “feel” appears on the screen. But at the same time, a new set of feeling-type words appears on the Activity Row.

Thus it is possible to generate “I feel hungry” or “I feel thirsty” with one key per word. This is a feature called Sentence Completion and a number of the keys in the Core will produce new vocabulary in the Activity Row.
