for screen readers. To access an accessible version, on the Interactive Tree menus click:
View > Accessible Window
This displays a view similar to the standard tree map, but one which JAWS can read correctly. You
can move up, down, right, or left using t he standard arrow keys. As you navigate the accessible
window, the f ocus in the Interactive Tree window moves accordingly. Use the Spacebar to change
the selection, or use Ctrl+Spacebar to extend the current selection.
Tips for Use
There are sev
eral tip s for making the IBM® SPSS® Modeler environ ment more accessible to you.
The following are general hints when working in SPSS Modeler.
Exiting extended text boxes.
Use Ctrl+Tab to exit extended text boxes. Note: Ctrl+Tab is also
used to exit
table controls.
Using the Tab key rather than arrow keys.
When selecting options for a dialog box, use the Tab
key to move between option buttons. The arrow keys will not work in this context.
Drop-down lists.
In a drop-down list for dialog boxes, you can use either the Escape key or the
Spacebar to select an item and then close the list. You can a lso use the Escape key to close
drop-do wn lists that do not close when you have tabbed to another control.
Execution
status
. When you are running a stream on a large database, J AWS can lag behind in
reading the stream status to you. Press th e Ctrl key periodically to update the status repo r ting.
Using the node palettes.
When you first enter a tab of the node palettes, J AWS will sometimes
read “groupbox” instead of the name of the node. In this case, you can use Ctrl+Right Arrow
and then Ct
rl+Left Arrow to reset the scre en reader and hear the node name.
Reading menus.
Occasionally, when you are first opening a menu, JAWS may not read the first
menu item. If you suspe ct that this may have happened, use th e Down Arrow and then the
Up Arrow to hear the first item in the menu.
Cascaded menus.
JAWS does not read the first level of a cascaded menu. If you he ar a break in
speaking while moving through a menu, press the Right Arrow key to hear the child menu
items.
Additionally, if you have IBM ® SPSS® Modeler Text Analytics installed, the following tips can
