Listbox (Moving Items to another listbox)

[NOTSOSURE]

Hey I’m trying to move multiple items from one listbox to another and vice versa but with my code now it only moves one at a time

Here is my code:

        ListBox2.Items.Add(ListBox1.SelectedItem)
        ListBox1.Items.Remove(ListBox1.SelectedItem)
        Button3.Enabled = False
        Button5.Enabled = False

any suggestions would be grateful
