Re: We require a property that is only used for explaining how to operate with keyboard. (Comment 363)

It may but I would be concerned about the length of text required when it
is simply an attribute.

This request may be addressed by Issue 406: aria-help proposal, currently
slated for ARIA 2.0.

users should be informed how to operate individual UI elements or blocks as
necessary when the focus is on those elements or blocks. Users highly
likely know how to operate the keys for such widgets that can be defined
under the roles of WAI-ARIA-for example TabPanel and Tree-because they are
widely used. However, it is difficult to build a feature- multifunctional
RIA using only the widgets defined in WAI-ARIA. Therefore, uncommon key
operations are sometimes required in order to make all functions operable
via a keyboard. Customizing a widget often not only makes the key operation
unclear, but also confuses users due to the difference between the key
operation detected by users or screen readers and the actual operation.

guidance of keyboard operation when that operation is not well known by
users. But, aria-describedby property is essentially intended as
supplements to labels. So, users cannot know just for a keyboard guidance.
They will be forced to be shown a guidance of key operations with
irrelevant information.

browsers to be able to display the content of the property only when the
key focus is on an element, because this would allow operating instructions
to be conveyed to users who are viewing the screen but using only keyboard.
And also, we whold like screen readers to be able to read aloud the content
of the property only when users require.
