The Single-Hit overlay contains a number of pictures with words
written underneath. Selecting a key will speak the word. Sometimes, the
key will also produce new single-hit words on the display of the Pathfinder
in what’s called the ‘Activity Row.’
The Activity Row is a line of 8 icons along the bottom of the Pathfinder
display that can contain any of some 2300 images. And if this isn’t enough,
new images can always be imported.
