Pushbutton LEDs will be updated to indicate which pushbutton presses are still valid
as each navigation pushbutton press event is processed. For example, a lit Up
pushbutton LED indicates there are pages above the current one.
3.3.3 Edit Mode
Edit mode edits the right display area and allows the user to alter control
parameters that define the Multi-Format Receiver behavior. To enter Edit mode
press the Edit pushbutton when on a page containing an editable control parameter
and the front panel is the controlling user interface. Edit may be entered on some
special pages at all times, for example on the page defining the controlling user
interface.
The Front Panel returns to Navigate mode when Edit is pressed again (abort edit
with no save) or when Save is pressed (save modified parameter values).
Processing of events from the front panel event queue depends on the current
operating mode of the front panel.
