Well... you could always combine the 'goto' key with some keyboard
shortcuts...

Lets assume that your cursor is in A3 and you want to select  the range
from A3:B1003. Touch function key 5 (F5). A 'go to' dialog box will
pop up. Type in A1003 in the reference box. BUT before you touch enter
key or hit the OK button... hold down the SHIFT key. Doing this will
select every cell between A3 and A1003.
