Is there a document, help command, or book that explains in some reasonable detail every dialog (text entry areas, check box, push buttons, radio buttons,tabs, list display, slider, graphic area, etc.), menu item and other operations in some detail? I'm aware of the method for identify an item by hold the cursor over it and the arrow question Mark selection. For example, these methods do not seem to apply to Preference items under Options. Nor are they applicable when right-clicking in a track. They are not available in Event Pan/Crop.
