I am in a bit of a pickle. I am using a Dell keyboard with Mac OS X, and I would like access to my function keys while I'm using Terminal. A friend of mine has a new Mac keyboard which has a Fn key right on it, but when I press the same location on my keyboard my cursor simply turns into a question mark, apparently this is treated as the 'help' key from older model mac keyboards.
I know that I can change my function keys to work properly using an option from the Keyboard preference pane, but I don't want to do that because the ONLY time I need my function keys is when I'm in terminal, other times I am fine with things like volume adjustment etc. so I'd rather have a Fn key. I have also looked in "Modifier Keys . . .", and it allows you to redefine the caps lock, ctrl, alt and shift keys, but not assign anything to Fn (which is a shame, I use Caps Lock as my Ctrl and the 'real' Ctrl would be a perfect Fn key)
So...is there any way to 'press Fn' on older mac keyboards or on third party keyboards?
EDIT: To clarify, my dell keyboard does NOT have a Fn key on it. The place on my friends Mac keyboard that functions as an Fn key is an Insert key on mine.
