Select Cell Range Relative To Starting Position

I need to change multiple conditional formats which apply to cell ranges 1 row x 17 columns wide. The specific change I am making is able to be acrried out with the code

With Selection.FormatConditions(1).Font
.ColorIndex = xlAutomatic
End With

However, I dont want the user to have to manually select each 17 cell area. I WANT THE USER TO JUST MANUALLY SELECT THE FIRST OF THE 17 CELL AREA. I want to write a macro that will THEN select a row of cells, 17 cells long, from the MANUALLY SELECTED position as at the moment of running the macro. Unfortunately the cells are not always on the same row in each sheet. On one sheet they may be on row 5, on another row 8 and on another, row 15 etc. I was wanting to be able to select a 17 cell range 'relative' to where the cursor is. How do I write the code to select the relative cell range? Is there an answer in an R[1]C[1]:R[1]C[17] sort of code?
