On the Map menu bar, select Post | Post Horizon/Fault | Current Horizon/Fault (or press <c> on your keyboard).
The Map window will display the active horizon/fault. This is particularly useful when you are picking several different horizons/faults in the seismic window and wish to quickly post the current horizon/fault in the Map window.
On the Horizon tab of the Object Manager bar, double-click on the horizon or fault. ProductName posts the event in the Map window, and the Horizon tab now displays an open eye beside the event. View image
You can use shortcut keys to quickly cycle through the horizons/faults in your project.
