event MouseMove (Button as Integer, Shift as Integer, X as OLE_XPOS_PIXELS, Y as OLE_YPOS_PIXELS)
Occurs when the user moves the mouse.

TypeDescription
Button as Integer An integer that corresponds to the state of the mouse buttons in which a bit is set if the button is down.
Shift as Integer An integer that corresponds to the state of the SHIFT, CTRL, and ALT keys.
X as OLE_XPOS_PIXELS A single that specifies the current X location of the mouse pointer. The x values is always expressed in container coordinates
Y as OLE_YPOS_PIXELS A single that specifies the current Y location of the mouse pointer. The y values is always expressed in container coordinates
The MouseMove event is generated continually as the mouse pointer moves across objects. Unless another object has captured the mouse, an object recognizes a MouseMove event whenever the mouse position is within its borders. Use the PageFromPoint property to get the page over the cursor.

The following sample underlines the page's caption while cursor hovers it :

Dim iHot

Private Sub Unhover(ByVal i As Long)
    With Tab1
        If (i >= 0) Then
            .Pages(i).Caption = Replace(.Pages(i).Caption, "<u><fgcolor=666666>", "")
        End If
    End With
End Sub

Private Sub Hover(ByVal i As Long)
    With Tab1
        iHot = i
        If (i >= 0) Then
            .Pages(i).Caption = "<u><fgcolor=666666>" + .Pages(i).Caption
        End If
    End With
End Sub

Private Sub Tab1_MouseMove(Button As Integer, Shift As Integer, X As Single, Y As Single)
    Dim i
    With Tab1
        i = .PageFromPoint(-1, -1)
        If (Not iHot = i) Then
            Unhover (iHot)
            iHot = i
            If Not (i = .Active) Then
                Hover (iHot)
            End If
        End If
    End With
End Sub

Private Sub Tab1_Activate(ByVal NewActive As Long, ByVal OldActive As Long)
    If (NewActive = iHot) Then
        Unhover iHot
        iHot = -1
    End If
End Sub

Private Sub Tab1_MouseLeave()
    If (iHot >= 0) Then
        Unhover iHot
        iHot = -1
    End If
End Sub

The following sample prints the page's key  over the cursor:

Private Sub Tab1_MouseMove(Button As Integer, Shift As Integer, X As Single, Y As Single)
    With Tab1
        Dim p As Long
        p = .PageFromPoint(-1, -1)
        If (p >= 0) Then
            Debug.Print "The cursor is over the page '" & .Pages(.Pages.PosToIndex(p)).Key & "'"
        End If
    End With
End Sub
