Ctrl+pgup pgdn can't jump worksheets
 

Hi, I'm having a problem in excel with the ctrl+pgup (jump betw
worksheet). the ctrl button works for ctrl+v and navigation and other
functions. also i can jump betw worksheets with the above, if i have
input an = in a cell. any ideas for getting my ctrl key working again
for jumps without having to input an = into a cell?

Thanks

Ed
