Audio/Video Control (AV/C) Transactions
Some AV/C transaction row fields are listed in the following table.

Several of the fields in AV/C transaction rows contain a View Fields command that allows
you to see the contents of the data structures.
Left-click* on the field header to access the cell context menu, which contains the View
Fields commands. Selecting the command opens a View Fields dialog, which contains the
data laid out according to the AV/C specification.
*If the option Right click cell context menu is checked on the General tab of the Display Options dialog,
then the cell context menu is opened by right-clicking. See Section 5.1.1, “General Display Options” on
