Is there a way to DISABLE the shortcut key (ctrl+D) which is Fill Down? I am
needing to use ctrl+F frequently and sometimes I accidently hit ctrl+D and my
spreadsheet is so huge that it locks up when I do that, then I loose all my
changes. It takes a while to save, so it is impractical to save after ever
change I make. Thanks for your time and any help you can suggest will be
appreciated!
