Hook Hear it!

Hook definition - hacker
An area in the message-handling mechanism of a computer system in which an application can install a subroutine to monitor the message traffic in the system. This application can also process certain kinds of messages before they can reach the targeted window procedure. Hooks significantly slow down computer systems because they increase the amount of processing that the system must perform for each message; therefore, they should be installed only when necessary.
