What do the Function keys after F12 do?

Question

While looking at a keyboard remapping program, I saw that one can remap keys from F13 to F24 as well. What do those keys do?

Answer 1

They dont do anything, but can do anything.

Function keys are soft keys. Basically, their functionality is based on whatever program is running. For example, you might press F2 when you turn your computer on to go into BIOS. However, once Windows loads, hitting F2 will rename the current file if you are the File Explorer, or rename the currently selected desktop icon. However, you might launch a program and the F2 saves the file you are working on in that program.

Keyboards with 24 function keys, F13 through F24 do exist, but are extremely rare. Since those keyboards are not common, programmers typically do not assign any functionality those keys. Since no one is likely to have keyboards with them, why would they? More than likely, the programmers themselves dont even know these keyboards even exist. However, since they do, the functionality to use them is available, like in your keyboard remapping program.

Answer 2

In case anyone is googling for help, the F16 key has a use in Excel (clears the current field).

Took me too long to figure out that my Windows stay awake function (which pressed F16 because I believed statements like the above, i.e. that they have no function) would clear the current cell every 30 seconds.
