A little more information in your question would be helpful. I assume you have the Editor open because you want to edit the feature. I assume you want to edit the specific feature because you clicked on it with the Editor widget active. The pop-up lets you edit attributes and/or attachments, thus I assume you don't want to do that. So I am going to guess you want to edit the feature by moving or deleting it. To select a feature without clicking on it, you use the selectfeatures tool from the Editor tool bar and either click on the item or draw a box around the feature to select it without opening the popup. You could then move or delete the feature (again assuming you had permission to do so). I hope this helps.
