I would like all of the workbooks, both new and old, to open at 85% zoom
instead of the default 100%. Is this possible? How? Thanks for your help
in advance.

Saved from a previous post (you'll have to adjust the percentage):

For brand new workbooks, you could create a book.xlt workbook template (stored
in your XLStart folder) that has each window the way you want.

If you want existing workbooks, then ...

Create a new workbook.
Add this code to the ThisWorkbook module:

Option Explicit
Public WithEvents xlApp As Application
Private Sub Workbook_BeforeClose(Cancel As Boolean)
Set xlApp = Nothing
End Sub
Private Sub Workbook_Open()
Set xlApp = Excel.Application
End Sub
Private Sub xlApp_NewWorkbook(ByVal Wb As Workbook)
Call DoTheWork(Wb)
End Sub
Private Sub xlApp_SheetActivate(ByVal Sh As Object)
Call DoTheWork(Sh.Parent)
End Sub
Private Sub xlApp_WorkbookOpen(ByVal Wb As Workbook)
Call DoTheWork(Wb)
End Sub
Private Sub DoTheWork(Wb As Workbook)
Dim myWindow As Window
For Each myWindow In Wb.Windows
myWindow.Zoom = 75
Next myWindow
End Sub

Save this file as an addin in your XLStart folder.

Each time you create a new workbook, open an existing workbook, change to a new
sheet, it'll set the zoom to 75%.

If you're new to macros:

Debra Dalgleish has some notes how to implement macros he

David McRitchie has an intro to macros:

(General, Regular and Standard modules all describe the same thing.)
