3.3.3 Edit Mode
Edit mode edits the right display area and allows the user to alter control
parameters that define the TT1260 behaviour. 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.
