Almost anyone who has used a word processor has accidentally hit the Insert key and overwritten when they thought they were editing. This article describes a simple way to disable the Insert key on your keyboard.
Whenever you press a key, a windows message is created, which contains a key code that uniquely identifies the key pressed. Programmes (like Microsoft Word) look for keypress messages and take actions based on the key code in the message. By mapping the insert key press event to null, windows send a message containing null for the key code when the Insert key is pressed. Programmes receiving the message, therefore, do not perform the action associated with an insert key press event, freeing you from having to worry about overwriting things again.
Make sure you read the warnings section before you continue.
