Repeater
From ISBoxer
Repeater is a part of ISBoxer that is responsible for 1-to-1 Key and/or Mouse broadcasting. This is typically enabled only temporarily, such as to enter the same password into multiple game windows, or to click through quest dialogs in multiple game windows. However, it is also easier for some people to configure a black or white list for Repeater than to create Mapped Keys, so it is also somewhat typical to be used most of the time.
