VBA, Excel - Find Range, Sort

Please correct my macro:

Application.Goto Reference:="AAA"
ActiveCell.Resize(xlDown, 9).Select

I'm trying to write a macro to find a named range, then highlight the rows
(?) down to the last cell and to the right (col) 9 columns so I can sort it
ascending (header is AAA).

I can copy the macro for the sorting by doing it step by step but I don't
know how select the range.

Thanks you.
