Translators: If this checkbox is checked, then Orca will speak the name of the
chat room prior to presenting an incoming message.

Translators: This is the label of a radio button. If it is selected, Orca will
speak all new chat messages as they appear irrespective of whether or not the
chat application currently has focus. This is the default behaviour.

Translators: This is the label of a radio button. If it is selected, Orca will
only speak new chat messages for the currently active channel, irrespective of
whether the chat application has focus.

Translators: This is the label of a panel holding options for how messages in
this application's chat rooms should be spoken. The options are: Speak messages
from all channels (i.e. even if the chat application doesn't have focus); speak
messages from a channel only if it is the active channel; speak messages from
any channel, but only if the chat application has focus.

Translators: In chat applications, Orca automatically presents incoming
messages in speech and braille. If a user is in multiple conversations or
channels at the same time, it can be confusing to know what room or channel
a given message came from just from hearing/reading it. For this reason, Orca
has an option to present the name of the room first ("#a11y <joanie> hello!"
instead of "<joanie> hello!"). This string to be translated is presented when
the value of the setting is toggled.

conversation has been added to the existing conversations. The "tab" here
refers to the tab which contains the label for a GtkNotebook page. The
label on the tab is the string substitution.

Translators: these are labels from the gedit spell checking
dialog and must be the same strings gedit uses.  We hate
keying off stuff like this, but we're forced to do so in
in this case.
