How to disable the Insert Key

On a laptop, especially - but also on some compact desktop keyboards - it's way too easy to accidentally hit the Insert key and find yourself typing over what you already typed - ouch! There are times when it comes in handy to be able to overtype, but if you never use it, you can prevent this from happening by disabling it.
For most programs, this registry edit works:
In your registry editor, navigate to HKEY_LOCAL_MACHINE \ SYSTEM \ CurrentControlSet \ Control \ Keyboard Layout
In the right pane, right click an empty space and select New and then Binary Value.
Name it Scancode Map
Double click it and in the Value Data field, add these values:00 00 00 00 00 00 00 0002 00 00 00 00 00 52 E000 00 00 00
Close the registry editor and reboot the computer

To disable the Insert key in Word 2003, do the following:
Click Tools Customize
Click the Keyboard button at the bottom
In the Categories box, scroll down and click All Commands
In the Commands box, click Overtype
In the Current Keys box, highlight Insert, then click the Remove button at the bottom.
Close all the dialog boxes

Note that in Word 2007, overtype is already disabled by default.
