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 associated with
the command to toggle room name presentation on or off.
