i am using vs.net 2003

i had set the keyboard mapping scheme as "visual basic 6" under
Tools-->Options-->Envirinment-->Keyboard

now i am able to use the shortcuts which were applicable in visual basic 6.

But "Cntrl + down key" and "Cntrl + up key" does not work

in visual basic 6 IDE, it is used to navigate between subs/functions in a module.

what is the equivalent shortcut in vs.net 2003 ?

please can anybody help ?
