Excel also supports Multiplan-style RC syntax for cell addresses, if you like. I find the syntax a bit more clear, but ultimately too verbose to be useful.

R1C1 = Row 1, Column 1. R[1]C[1] = cell one row over and one row down.

One other point worth mentioning is that cell-relative references in Excel are more pervasive than they might appear. For example, you can specify a conditional format formula that highlights a cell if it has a different value than the cell immediately above. (Or a number of other more considerably complex scenarios.)

Range names work this way too... it's possible to define a range of the form "three cells to the right of the current cell".

Multiplan... now that's a name I haven't heard in a long time.
