I'm assuming you do mean Worksheet, as stated, and not Workbook.

Anyway, you can use some code to do this. I've previously done something
like this with the following:

First, create a sheet named "Data". This sheet can be hidden if you'd like.
Next, press Alt+F11 to bring up the VB editor.
Double-click on "ThisWorkbook".
Paste the following code:

Private Sub Workbook_SheetDeactivate(ByVal Sh As Object)
Sheets("Data").Range("A2").Value = Sheets("Data").Range("A1").Value
Sheets("Data").Range("A1").Value = ActiveSheet.Name
End Sub

Next, right-click "ThisWorkbook" again and goto "Insert" and then select
"Module".
Paste the following code:

Sub ActivateLastSheet()
Sheets(Sheets("Data").Range("A2").Value).Activate
End Sub

Close the VB Editor window.
From your Excel window, click Tools-Macro-Macros.
Select ActivateLastSheet and then click Options.
In this section you can assign a short-cut key to easily access the code
that activates the previous sheet you were on.


Hope this is helpful.

Is there a quick way to open the last worksheet you had open prior to the
one
you are currently viewing, and toggle between the two sheets? I am
looking
for something like the alt+tab command for windows.
