In the dashboard, navigate to your project and click the “Start app preview” button. A modal window will appear, in which you select the target platform to start preview on. To preview from Sublime Text, right-click any .ux or .unoproj file in the sidebar and select your target platform under the Fuse: Preview menu. You’ll want to pick the “local” target, which will bring up the desktop simulator.

Keep in mind I’m not entirely sure what “fuse example” you’re referring to; so it might be one that only runs on devices.
