KeyState

KeyState is a new batch file utility that allows you to easily determine if a key is being held down when the batch starts or at any time during execution. For example, you could have a batch file behave differently if the user holds the Control Key down while launching the batch.

In addition, options in KeyState allow a batch to change the CapsLock, NumLock, or ScrollLock states. For example, if you are prompting for a password, you could programmatically turn off the CapsLock before prompting for the password.
