Is there a simple way for a cell formula to refer to its own cell?

I can get my own column by using =COLUMN(), I can get my own row by
using =ROW(). How can I get my own CELL ?

I like to use C1=OFFSET(C1,-1,0) as a cut/copy/paste/delete-safe
formula which refers to the value immediately above the current cell.
The only trouble is in discussing formulas with others. I cannot say
"use =OFFSET(B44,-1,0)" without further saying that that formula will
only work in cell B44.

Is there an equivalent to =OFFSET(ME(),-1,0) ?

I have tried =OFFSET(,-1,0) but that is a syntax error.

The best I have yet come up with is the following:

=INDIRECT(CONCATENATE("R",TEXT(ROW()-1,0),"C",TEXT(COLUMN(),0)),0)

Can anyone do it better?
