Browsing Chinese (Hong Kong) translation

Translators: A live region is an area of a web page that is periodically
updated, e.g. stock ticker. http://www.w3.org/TR/wai-aria/terms#def_liveregion
This string refers to an Orca command which allows the user to toggle whether
or not Orca pays attention to changes in live regions. Note that turning off
monitoring of live events is NOT the same as turning the politeness level
to "off". The user can opt to have no notifications presented (politeness
level of "off") and still manually review recent updates to live regions via
Orca commands for doing so -- as long as the monitoring of live regions is
enabled.
