Translators: Orca uses Speech Dispatcher to present content to users via text-
to-speech. Speech Dispatcher has a feature to control how capital letters are
presented: Do nothing at all, say the word 'capital' prior to presenting a
capital letter, or play a tone which Speech Dispatcher refers to as a sound
'icon'. This string to be translated refers to an Orca command which makes it
possible for users to quickly cycle amongst these alternatives without having
to get into a GUI.

Translators: Orca has an "echo" setting which allows the user to configure
what is spoken in response to a key press. Given a user who typed "Hello
