Move item from 1 listbox to another listbox

Hello,

need help on an excel listbox using vba.

i've got 2 listboxes on a form. listbox1 is being populated from an excel sheet. i need to move items (either one by one or all items) from listbox1 to listbox2 on a single click and also have the ability to remove items from listbox2(either one by one or all items). any help would be appreciated.

thanks
