Just curious, why do you want this? This is going to cause a significant slow-down in how fast you can enter data, and also remove the ability to "undo" any mistakes.

Hi!
Maybe the OP wants to get sure to don't lose any entered data ever again, what he might not know is the cost to be paid. Let him give a try (aka wait & see, I'd bet on no more than 10 minutes of use with this method).
Regards!
