“Undo” feature in Visual Studio 2008 stops working

Question

I\'ll be coding along in Visual Studio 2008, and eventually I make a mistake. I press CTRL - Z to undo and NOTHING HAPPENS. I\'m not talking about anything

Answer 1

I had this in visual studio 2008SP1 - one day the undo function just completely stopped working. Looking at a previous posters comment, i just did :

Tools -> Option -> Environment -> Keyboard Press Reset

After restarting visual studio, undo now works.
