I'm not sure why the game doesn't respond to the F10 button.
For the list above I just added what I thought would be the most useful spells from what my character knew, to have a better chance matching some of what Price wanted to assign hotkeys to. I only ever used about 5 function hotkeys: F1 for minor healing potions at first, then minor restoration potions, F4 for Restoration and 3 others for Lockpick, Spellshield and Aura of Guarding (the last two I just used for a stretch in the middle of the game).
Another possible workaround for the function key problem is to map some of the function keys to other keys. In Windows XP, this can be done using a program like
KeyTweak. For Win 9x, MS included such a utility in their
Kernel Toys. There is a warning that they are not intended for Windows 98, but at least the Keyboard Remap tool should work fine.
