Hi,
Thanks for the answer, this makes a little more sense so
continuing this
so how should it work if you have items which are embedded in other
controls
e.g. Large amount of text in a list box, or say options which are
grouped
within a group box.
The Item Chooser Menu builds a list of all elements, even nested
elements. So each individual AXUIElement would be represented by a
line in the menu. Large blobs of text in an element, such as an
AXTextArea, would still be represented as one menu item (you would
get a one line entry that is basically a truncated version of the
large blob of text). But AXLists and AXTables can have many
children, and the Item Chooser should show each child element.
Was this question still about the item chooser, or general navigation
with VO?

Thanks
Mark.
The item chooser menu provides a user with a list of all (accessible)
elements in a window. It is intended to be a supplemental screen
navigation technique. Sighted folks generally navigate a user
interface by glancing around the screen, quickly identifying an
element of interest, and then moving the mouse to it or tabbing until
the focus loop moves to it. This technique is generally very
efficient.
Most VoiceOver users do not use vision to navigate. Instead they
move from item to item using the VoiceOver cursor, and listen to a
description of each item. Since moving from item to item can be more
tedious, we introduced the Item Chooser Menu as an alternative. The
user can press control-option-i to open the Item Chooser Menu. They
can then arrow through each element, or more typically, they can type
a few characters to narrow the list. Once the list is narrowed, they
can arrow over one or two items that are similarly spelled to find
what they are looking for. With practice, a user can significantly
reduce the number of keystrokes necessary to move around.
To navigate elements based on their screen location, simply use
control+option+arrows.
