What do you mean by "edit button"? That is not an official term in the Access world.
Put a form in design view. In the ribbon, Form Design is now the active tab. It has a section "Controls" will all the controls that are available to be put on your form (you may need to use the scrollbar at the far right of this section to see more). There is a Button (a.k.a. Command Button), and a Toggle Button (rarely used). Will those work for you? If not, explain more.
