copy / paste using ctrl-c and ctrl-v

[Russell Nelson]

I would like my users to be able to select tree entities, copy them using ctrl-c, move the focus elsewhere, then copy them using ctrl-v. Had to play around a bit, but this is working for me:

    $('#left').jstree({

    'core' : {

      'keyboard': {

          'ctrl-x': function(e) { options_cut(); },

          'ctrl-c': function(e) { options_copy(); },

          'ctrl-v': function(e) { options_paste(); },

        },

      },

I don't need the event because I use the selection.
