hovering with cursor

I think you will need vba to do that. I've never done it myself, but I think this may get you started:

Option Explicit

Public Declare PtrSafe Function GetCursorPos Lib "user32" (lpPoint As POINTAPI) As Long

Public Type POINTAPI
     x As Long
     y As Long
End Type

Sub TrackCursor()
     Dim mousePos As POINTAPI
     Dim curCell As Range
     Dim target As Range
     
     On Error Resume Next
     
     '//  Change where/how to display it as needed.
     Set target = Sheet1.Range("A1")
     
     Do
          GetCursorPos mousePos
          Set curCell = GetRangeFromXY(mousePos.x, mousePos.y)
          target.Value = curCell.Address
          DoEvents
          
          '//  You may set up a check here for some trigger
          '//  (maybe a cell that is TRUE/FALSE) to break
          '//  out of the loop and exit the procedure.
          
     Loop
End Sub

Function GetRangeFromXY(x As Long, y As Long) As Range
    On Error Resume Next
    Set GetRangeFromXY = ActiveWindow.RangeFromPoint(x, y)
End Function
