This is probably documented somewhere – it is a standard feature of Eclipse – but I thought I would mention that if you want to view and/or edit the properties of a launch configuration (you know the Run > Debug… or Run > Run… dialog), a shortcut to do that is to click the Debug or Run dropdown icon on the toolbar, and then control-click on the configuration you want to edit. A regular click, of course, will launch that configuration; but a control-click will bring up the dialog to edit it.
