Accelerators are
a form of selection-based search which allow a user to invoke an
online service from any other page using only the mouse introduced by Microsoft in Internet

objects will give users access to the usable Accelerator services (such as
blogging with the selected text, or viewing a map of a selected geographical
location), which can then be invoked with the selected object. According to Microsoft,
Accelerators eliminate the need to copy and paste content between web pages
