Remarks Creating custom code for cutting requires several steps:
- Set event.returnValue=false in the onbeforecut event to enable the Cut shortcut menu item.
- Specify a data format in which to transfer the selection through the setdata method of the clipboarddata object.
- invoke the setdata method in the oncut event.
