Hi,

When the user selects "Pages" radio button in the Range section, it is very
reasonable to expect that she would now want to specify the range. Thus moving
the focus automatically to the page range edit box would save the user a mouse
click.
Unrequested focus changes that are not announced in advance are not
good practice for accessibility reasons.
1. When a screen reader user (typically a blind user) encounters a
set of radio buttons, the only way to find out what the buttons are,
is going through them with the up/down arrow. If the focus changes to
the page range input field when she puts the focus on the Pages radio
button, the label for the radio button will either not be read by the
screen reader or the labels for the radio button and the edit field
will be run together, which might lead to confusion.
2. Keyboard users (not only blind users) move through dialogs like
the Print dialog with the Tab key and the Shift+Tab key. The latter
is for navigating backwards. With this patch, what happens when the
user presses Shift+Tab from the Page Range field in order to move
back to the radio buttons? Does the focus immediately get pushed back
to the edit field, making backwards navigation impossible?
Best regards,
Christophe
