Why not just map the Home and End keys to some other keys that the game doesn't use?
(and use keys that don't require pressing the Fn key)

Keymapper does not offer the function key on the map therefore I cannot assign it to another key. The key functionality I'd like to map to other keys requires a key combination - function + home and function + end. I'd like to assign function + home to the '>' key and function + end to the '<' key. However, since keymapper requires the "purpose" keys (fn + home and fn + end) to start the process of binding and the keys to be "binded" to (<,>) second and I cannot locate the function key I can't do a simple assignment.

I believe the steps required are:
select fn + home 'because there is no 'function' or 'fn' keys on the keymapper I cannot continue with assignment
select add
select '>'
save

Maybe I'm just not understanding this correctly but isn't this what you want:

Q1. You want to have the "X" on your keyboard to type a "Home" in DOSBox.
A. Click on the "Home" on the keyboard mapper. Click "Add".
Now press the "X" key on your keyboard.

No need for the fn key in any step.

On my keyboard, the home key is on the same key as the PgUp key and the end key is on the same key as the PgDn key. To access home and end I need to activate the Fn key at the same time - Fn + home and Fn + end. There is no Fn key on the keymapper. Mod1 accesses Alt and Mod2 accesses Ctrl, Mod3 seems to access nothing. The Add button is used to bind new functionality to a key and requires that the event be specified before the key to be binded to:

You don't need to "activate" the fn key. Just use your mouse and click the button marked "home" in the keymapper.

Correct me if I am wrong but that would map the PgUp functionality to a new key and I want to map the Home functionality to the new key (which normally requires me to use the combination of fn + PgUp). Consider the F1 to F12 keys at the top of the keyboard. On my computer each one provides two purposes - a system function like raising or lowering volume and a function number key which acts as a keyboard shortcut when used in combination with the function key. If I mapped one of these keys to another key I would be mapping the system function, how would I map the shortcut that requires the function key?

What I am saying is if the key has two purposes and relies on a fn + key sequence how would I map that functionality to a new key?

on the mapper screen, click home.
click "add"
press the key on your keyboard that you want to give the home functionality (e.g the f12 key without pressing fn)

done.

No, that would require clicking the button marked "PgUp" in the keymapper.
