is there a map of what the function keys do?

The context provided does not contain a specific map of what the function keys do in Windows 10. However, it does mention the mapping of function keys for the 5250 Client and the standard IBM 101 keyboard layout. For example, in the 5250 Client, function keys F1 to F12 are directly mapped to their corresponding keys on the Enhanced 101 keyboard. Additionally, there are mappings for keys like BACKSPACE, CURSOR keys, and others.

If you are looking for a general map of function keys in Windows 10, it may vary by application, and you might want to check the documentation for specific software or the Windows help resources for more detailed information on function key usage.
