I have a spreadsheet with the following macro in several sheets. It changes the
fill color of the active row to yellow. It's quite handy, as the sheet is a bit
wide so it helps me keep track of what row I'm working with. It has only one
drawback (well, two). When I first open the workbook or first activate another
sheet, the active row is, of course, yellow, but when I move off of that row or
click on another row, the initial row remains yellow. The sheet then has two
rows that are yellow and remains that way unless I scroll through the active
row. That is, make the initial active row active again and then go to another
row.
Also, I can't copy (or cut) and paste from one cell to another on the same
sheet and if I want to copy to another sheet, I first have to pre-select where I
want to copy to.
Here's the code. It's adapted from (I believe) Chip Pearson's website. My
apologies if it's someone else. Any help would be gladly appreciated.

Dim z As Long

Private Sub Worksheet_SelectionChange(ByVal Target As Excel.Range)
'Exit Sub
ActiveCell.EntireRow.Interior.ColorIndex = 6

If z = Empty Then
z = ActiveCell.Row
ElseIf Not z = ActiveCell.Row Then
Rows(z).EntireRow.Interior.ColorIndex = xlColorIndexNone
End If

z = ActiveCell.Row


End Sub
