Keys not function in Excel anymore

[realrookie]

Hello,

Had excel open and close several times today.. but now some keys do not what I expect them to do:
END - jumps to the last visible cell on screen (bottom right somewhere)
The arrow keys no longer switch cells, they just scroll now up/down/left or right.
Shift+arrow does nothing anymore
Crtl+arrow jumps a whole page...

Anyone any ideas?
