I want my keyboard back

Is there any way to use all the keys on the keyboard in fsx.
I like single key commands and had a perfect set-up for fs2004. Numpad was my auto pilot panel, arrows trim and PgUp, PgDn, Home, End, Ins, Del key cluster was like an engineers panel.
FSX seems to waste a lot of nice single key functions. Is there a way to change it?
