Hello Ron. Please help me better understand the issue. Am I correct in assuming that a BVI pilot currently uses the following keyboard commands... ALT F to open the Flights drop down list? ALT A to open the Aircraft drop down list? ALT W to open the World drop down list? ALT O to open the Options drop down list? If so, then why is it that... ALT D would not open the Add-on drop down list? Please advise. Thanks, Robert -- AOPA Member No: 06936977
