[OpenLayers-Users] How to disable <ctrl> drag

[Jan Hartmann]

This works:

var control = new OpenLayers.Control();
     OpenLayers.Util.extend(control, {
     draw: function () {
         // this Handler.Box will intercept the ctrl-mousedown
         // before Control.MouseDefault gets to see it
         this.drag = new OpenLayers.Handler.Drag( control,
             {"done": this.notice},
             {keyMask: OpenLayers.Handler.MOD_CTRL});
         this.drag.activate();
     },

     notice: function () {
         return(true)
     }
map.addControl(control);

Thanks Ryan,

Jan
