One of the easiest ways to navigate through FBO One is just to follow links.
For instance the order grid of the browse screen is full of links that can bring you directly to debtors, stations, orders or even individual services.
In the order screen, there are links to the aircraft registration, the aircraft type, the debtor etc.
Just follow the links.
In case you get lost, there's always the history, the main menu, main search box or 'return to order' link to get you back on track.
