As an editor working at a complex wiki (e.g., the English Wikipedia), I encounter many complicated and unfamiliar templates. Before I try to edit them, I want to look at the template page and read the documentation. In VisualEditor's visual editing mode, I want to be able to control-click or Command–click on the template to open the Template: page in a new browser tab.
