Keyblocking occurs when a co-worker places documents or memos on top of your keyboard in an office environment, with the purpose of forcing you to deal with said document before resuming internet activities at work. It is a coworkers way of saying "pay attention to this before doing anything else". Normally, multiple documents will pile up on one's keyboard that must be dealt with in turn before surfing the internet can continue.
