How to catch when the user clicks a cell?

Hello,

I have a simple yet tricky task I cannot really solve. I want to write a macro that makes green the background of that cell, which the user clicks. But I can't find any "click" event for a cell. Can this thing still be achieved somehow? It would be urgent, I need to finish this today or Monday at the latest.

Thank you a lot in advance.

Thank you a lot, you are great, it works for E1! Now just two short questions:

- How to modify the "If Target.Address = "$E$1" Then" line if I want this code to work for a range (let's say C12:S51)?

- Where do you know "Worksheet_SelectionChange" from? I couldn't find it in VBA's help.

Thank you.

Thank you!
