You could put a button from the control toolbox toolbar on that worksheet.
Double click on that button and you'll see where the code goes.

Paste this in that window and end up with something that looks like this.

Option Explicit
Private Sub CommandButton1_Click()
Dim myRng As Range

Set myRng = Me.Range("a3:a5,a7:a19,a22:a33")

myRng.EntireRow.Hidden = Not (myRng(1).EntireRow.Hidden)

End Sub

Adjust the range you want to hide/show

I want to group rows together and have a quick expand/collapse button on the
sheet itself. I see the group/outline function but do not like the display of
the expand/collapse in the left side of the rows.
