I need to change the cursor color; I can hardly see mine (currently light green). I tried Themes, Color, Effects on the Page Layout tab with no success. Any ideas would be greatly appreciated.

I need to change the cursor color

You can use the code ("Highlighting The Active Cell") below.

However, there is a downside:

There is one massive drawback, and that is that this technique will use something called "Event Procedures", which means that the macro will fire every time you move the cursor - and every time a macro fires it will clear your undo stack. So, yes, it is do-able, but you'll lose your undo facility.

The RowLiner add-in (by the same author as the code below) also looks interesting. This add-in has the same issue with undo:

RowLiner will disable the Undo feature. This is a limitation imposed by the basic design of Excel and cannot be changed.

Highlighting The Active Cell

If you want to make the active cell appear in a special color, use the
following code in the Workbook_SheetSelectionChange event of the
workbook.

Private Sub Workbook_SheetSelectionChange(ByVal Sh As Object,

    ByVal Target As Excel.Range)

    Static OldRange As Range

    On Error Resume Next

    Target.Interior.ColorIndex = 6 ' yellow - change as needed

    OldRange.Interior.ColorIndex = xlColorIndexNone

    Set OldRange = Target

End Sub

This will change the background color of the ActiveCell to yellow
anytime you select a new cell, either with the mouse or with the arrow
keys.

NOTE: This technique has been greatly enhanced in my RowLiner
add-in. I strongly suggest you use RowLiner instead.
