Tab into combobox with autocomplete drop down menu

Hello,

I have only just stared to delve into VBA coding and I have come across a problem that I cant seem to find an answer to yet. I am using a code I found online for creating and using a combox on top of a data validation menu that way it can be autocompleted when tabing into and out of cells while typing. This is for taking records over a CB radio about snow plow operations so the user needs to be able to type information fast and accurate. Right now it is set up to only activate when I double click the cell which is not efficient for data entry.

The code that works for the comboboxes is as follows:

'==========================
Private Sub Worksheet_BeforedoubleClick(ByVal Target As Range, _
  Cancel As Boolean)
Dim str As String
Dim cboTemp As OLEObject
Dim ws As Worksheet
Set ws = ActiveSheet
Set cboTemp = ws.OLEObjects("TempCombo")
  On Error Resume Next
  With cboTemp
  'clear and hide the combo box
    .ListFillRange = ""
    .LinkedCell = ""
    .Visible = False
  End With
On Error GoTo errHandler
  If Target.Validation.Type = 3 Then
    'if the cell contains a data validation list
    Cancel = True
    Application.EnableEvents = False
    'get the data validation formula
    str = Target.Validation.Formula1
    str = Right(str, Len(str) - 1)
    With cboTemp
      'show the combobox with the list
      .Visible = True
      .Left = Target.Left
      .Top = Target.Top
      .Width = Target.Width + 5
      .Height = Target.Height + 5
      .ListFillRange = ws.Range(str).Address
      .LinkedCell = Target.Address
    End With
    cboTemp.Activate
    'open the drop down list automatically
    Me.TempCombo.DropDown
  End If
  
errHandler:
  Application.EnableEvents = True
  Exit Sub

End Sub
'=========================================
Private Sub Worksheet_SelectionChange(ByVal Target As Range)
Dim str As String
Dim cboTemp As OLEObject
Dim ws As Worksheet
Set ws = ActiveSheet

Set cboTemp = ws.OLEObjects("TempCombo")
  On Error Resume Next
If cboTemp.Visible = True Then
  With cboTemp
    .Top = 10
    .Left = 10
    .ListFillRange = ""
    .LinkedCell = ""
    .Visible = False
    .Value = ""
  End With
End If

errHandler:
  Application.EnableEvents = True
  Exit Sub

End Sub
'====================================
'Optional code to move to next cell if Tab or Enter are pressed
'from code by Ted Lanham
'***NOTE: if KeyDown causes problems, change to KeyUp

Private Sub TempCombo_KeyDown(ByVal _
        KeyCode As MSForms.ReturnInteger, _
        ByVal Shift As Integer)
    Select Case KeyCode
        Case 9 'Tab
            ActiveCell.Offset(0, 1).Activate
        Case 13 'Enter
            ActiveCell.Offset(1, 0).Activate
        Case Else
            'do nothing
    End Select
End Sub
'====================================

I am wondering if there is a way to tab into the combo box from the cell to the left enter the info and tab out into a generic cell and back into another combobox etc as needed.

Cell A5 is where the records would start and I will have have the drop downs in colums B, C, D and G each with their own tables.

Please let me know if any more information is needed or if I need to upload the workbook.

Thanks,
