Don't display shortcuts if braille verbosity is set to brief
Don't display shortcuts if braille verbosity is set to brief

According to our documentation, the braille verbosity setting:

    determines the amount of information that will be brailled
    in certain situations. For example, if it is set to verbose,
    keyboard shortcut and role name information is displayed.
    This information is not displayed in brief mode.

We were always displaying shortcut information. Now we only display
shortcut information if the braille verbosity setting is verbose.
