The standard Opencockpits EFIS P&P modules do not have push buttons for CTR and TFC.
Both functions are implemented in the OCP4NGX and OCP4777X.
If you double click WPT you will emulate a CTR push and if you double click DATA you emulate a TFC push.
At some point in time this information vanished in the docs. Docs will be updated to annouce this important EFIS information.
