If in range, on Enter key -- select cell in column A, which is scrolled to top

[2Took]

I have top 8 rows frozen. When I'm in row 8 in K:S and if I press Enter key, I'd like a cell in column A to be selected in whatever row happened to be scrolled to the top.
Example: row 500 may be scrolled up and be immediately under top 8 frozen rows. If I press Enter key, while in Range("k8:s8"), code should select A500. If top row is 600, then A600 should be selected.
Code I have only selects specific, hard coded cell. And with that, not only when I press Enter while in Range("k8:s8"), but anywhere on the sheet.

Private Sub Worksheet_SelectionChange(ByVal Target As Range)
  If Not Intersect(Target, Range("k8:s8")) Is Nothing Then
    Application.OnKey "~", "OnEnterK8S8"
    End If
  End Sub

Sub OnEnterK8S8()
ActiveSheet.Range("A629").Select
End Sub

Try this.

    Range("A" & ActiveWindow.ActivePane.ScrollRow).Select

Try this.

    Range("A" & ActiveWindow.ActivePane.ScrollRow).Select

That worked... but now I still need to limit it to only when I press Enter when I'm in Range("k8:s8")

You already have the worksheet_selectionchange event set up, put it in there. Change the target to 1 row lower so when you hit enter it kicks in when you have K7:S8 selected

That's not a solution, because as is your great code line runs anytime Enter is pressed, no matter what cell is selected. But I did try your advice.
It's almost as though code is completely ignoring my attempt to limit when to run.
And it's Application wide, even though the code is only in one worksheet of one workbook (probably because of line "Application.OnKey").
Seems like that only returns to normal after Excel restart, which is another issue I need a solution for -- for this modified Enter key behavior to stop, and go back to normal, once selected/active cell is not within Range("k8:s8") on a worksheet containing the code.
