The equivalent in VBA of the Macro in that lesson is:

DoCmd.OpenForm "OrderF", , , "CustomerID=" & CustomerID
DoCmd.GoToRecord acDataForm, "OrderF", acNewRec

Docmd.OpenForm and GoToRecord are both covered in Access Developer 1.

There isn't a direct 1 to 1 video like in the Adv2 lesson.  I was all set to point you to the index but...

Richard has covered it in a couple of other areas though not that same exact example.  It's all about the Legos.
Whether you "Add New... (Customer, Order, Invoice Item, Appointment, etc) the process is the same.

Here are a couple of videos to get you started.  See if that gets you where you want to go.  
Hint look at the Advanced 2 #1 video again pay attention to the 'process'.

Add Records Automatically

Invoicing

There's a button you can press to convert a macro to VBA

Thansk, I converted the Macro to Visual Basic, the end result was this:

Function Macro1()
On Error GoTo Macro1_Err

    If (IsNull(Forms!OrderF!OrderID)) Then
        DoCmd.OpenForm "OrderF", acNormal, "", "", , acNormal
        DoCmd.GoToControl "OrderDate"
        Forms!OrderF!OrderDate = Now()
        DoCmd.RefreshRecord
        DoCmd.GoToControl "OrderDetailF"
        DoCmd.GoToControl "ProductName"
    End If


Macro1_Exit:
    Exit Function

Macro1_Err:
    MsgBox Error$
    Resume Macro1_Exit

End Function

The "Convert to visual basic" button was disabled, I followed this post to solve it: https://www.office-forums.com/threads/solved-in-access-2010-convert-macros-to-visual-basic-is-grayed-out.2085243/
