Call TAB and then ENTER keys in an Excel VBA module

Question

I hope I am doing this right. This is my first question on Stackoverflow and I am pretty raw when it comes to Excel.

In the code below I am opening 20 workbooks in succession. The problem I have is that each workbook requests the user to click "yes" to open as read only or "no" to allow editing. Thus I have to hit "TAB" and "ENTER" (or click "No") for each workbook.

I would like to automatically apply the TAB and ENTER from within the code (hands free)

'Name macro
Sub SearchWKBooks()
 
'Dimension variables and declare data types
Dim WS As Worksheet
Dim myfolder As String
Dim Str As String
Dim a As Single
Dim sht As Worksheet
 
'Create a new worksheet and svae it to object named WS
Set WS = Sheets.Add
 
'Show dialog box and ask for a folder
With Application.FileDialog(msoFileDialogFolderPicker)
    .Show
 
    'Save selected folder path to variable myfolder
    myfolder = .SelectedItems(1) & "\"
End With
 
'Show inputbox and ask for search string to use
Str = Application.InputBox(prompt:="Search string:", Title:="Search all workbooks in a folder", Type:=2)
 
'Stop macro if string is nothing
If Str = "" Then Exit Sub
 
'Save text "Search string:" to cell A1 on worksheet WS
WS.Range("A1") = "Search string:"
 
'Save text in variable Str to cell B1 on worksheet WS
