Accessibility in the Interactive Tree Window

The standard display of a d ecision tree model in the Interactive Tree window may cause problems

for screen rea ders. To access an acc essible version, on the In teractive Tree me nus click:

This disp lays a view similar to the standard tree map, but one wh ich JAWS can read correctly. You

can move up, down, right, or left using the standard arrow keys. As you navigate the accessible

window, the focus in the Interactive Tree window moves accordingly. Use the Spacebar to change

the selection, or use Ctrl+Spacebar to extend the current selection.
