As asked in this question, I am used to pressing Fn+Left on my laptop's keyboard to simulate the Home key and Fn+Right for End.

However, I have a wireless keyboard with physical Home and End keys, and using these keyboard shortcuts Fn does not work on it.

Is it possible to assign custom Fn keyboard shortcuts in Windows? I would also like to change, if possible, some of the other shortcuts on my wireless keyboard that involve the Fn key, so that this keyboard is set up the same way as the laptop's built-in keyboard.

    Does this answer your question? Remap FN to another key

    Keys cost money. The reason you have to press Ctrl+Alt+Delete to logon is because an IBM engineer in charge of keyboards refused Microsoft's request for a logon key on cost grounds. Laptop manufacturers use the Fn key to typically (as all are different) map App keys to Function keys. On my computer - I press F11 and IE will go full screen because the keyboard send the F11 key to Windows. I press Fn+F11 it send the app key volume up. Fn and power keys are not part of the keyboard. There are three types of keys that relate to newer keyboards. Nov 18, 2021 at 4:18
  • They are equivalent to each other only and are distinguished from when there were introduced. 84 key keyboards (page up etc are on the numeric keypad), 101 key keyboards (dedicated page up/insert keys), and app keys (volume etc). Nov 18, 2021 at 4:22

I am not quite certain I fully understand what you want to do, but, in short, I would suspect you're likely out of luck regarding anything having to with Fn keys. Function keys are often hardware-based, rather than software-based, so it isn't necessarily possible to emulate them.
