Make F4 key be Ctrl-C (copy)

Instead of doing Ctrl-C for copy, I would like to make my F4 function key do this instead. How to set Function keys in Windows 7?

Or is there a program that I need to install?

KeyMapper might work for you.

KeyMapper does not seem to work with double-key combinations.

Since when was F4 a double-key combination?

The real problem is that Copy isn’t one of the options that KeyMapper allows you to map.

You could use AutoHotKey to map the F4 to ctrl-C using: F4::^c

That would send a ctrl-c to the computer every time you press the F4 key.
