I need to copy a range of cells, but I don't know the cell I'm in.

For example, I may be cell "A6". I want to select and copy X number
of cells down. Every example shows 'Range("A6:A45").Select.' What I
need is something like 'Range(fromThisCell:toThisCell).Select' Can I
use the Offset command somehow to select a relitive number of cells?

I have two files open, and I want to copy a range of cells from one
sheet to the next. The problem is the range of data will always start
in row 6, but the columns will vary.

Any help with this will be greatly appreciated. If I did not present
my question clearly, please e-mail me and I will elaborate.
