Change action of Tab in Microsoft Word

Please help, I need that when i press the tab key to move to a new line, similar to pressing the down key. Any ideas how to do it?

I tried to use autocorrect, but I don't know how to denote the tab character.

How about this:

Just run the Sub ShortcutKeys() should be done.

Sub TabisDown()
    Selection.MoveDown
End Sub
Rem assign the shortcut key tab(wdKeyTab) to the active Document to run TabisDoow sub which just do what the down key do
Sub ShortcutKeys()
    'if below line use NormalTemplate ,then you should add the Sub TabisDown() code above
    ' to your Normal.dotm Templates which is locate in the directory whose address is "%AppData%\Microsoft\Templates"
    ' or you use ActiveDocument instead to save the two sub code in a .docm document.
    ' the first way it will appact/apply on/to all documents,the other just on/to the document where the code is saved
    CustomizationContext = ActiveDocument 'NormalTemplate 
  '  ThisDocument
    KeyBindings.Add _
        KeyCategory:=wdKeyCategoryCommand, _
        Command:="TabisDown", _
        KeyCode:=BuildKeyCode(wdKeyTab)
End Sub

remark where to save and when to run is matter

If you want to save in Normal.dotm you should run the sub in it's modules, not in a document's modules. If you run this sub in some document ,and the Sub TabisDown() is there, then the saved sub will be the one saved in that documents,not in the Normal.dotm, then you have to open this document in every time, or the shortcut will be set , but the Sub TabisDown() will not be found, this results in pressing tab key and nothing happen. Or you can rename the TabisDown sub to a specific name to prevent that name conflict with the name in a .docm document file.

YouChat help me a corrected version of my text above with grammar and punctuation corrections:
