I need to input the entries in one column - ex: RF , RWW, RC, CTUM-NV,
It depends on the disposition on what code goes into that cell. But, they
are the same ones all the time. Is there a way to set-up a shortcut keys for
these.

I do not want to use drop down boxes because this is a huge spreadsheet.

We do not have Access, which that would of been my choice.

Any help would be greatly appreciated.
