I use accented letters regularly in informal and formal contexts in several languages and I need a number pad in order to type these. I purchased the Dell Studio 1555 without realising that the keyboard completely lacks an integrated numpad. I cannot swap back and forth between, say, standard Spanish and German keyboards because I use the Dvorak layout and feel that to force myself to change the layout I use natively just for a missing feature on a keyboard is not an actual solution to the problem.

Is there any way at all to assign fn number pad keys to, say, the top row? No combination of Fn, Shift, Num lock (reassigned F6 to it) allows me to type in alt codes.
