TrvActionFonts is the action for "Font" command. It uses a standard font dialog (TFontDialog).
TrvActionFonts = class(TrvActionTextStyles)
It's recommended to use TrvActionFontEx instead of this action because of two reasons:
•TrvActionFonts applies all font properties, it's not possible to leave some fields blank in TFontDialog. In TrvActionFontEx, if you open a dialog and press OK without changing anything, nothing will be changed in the selected text; this is not so for this action;
•TrvActionFontEx allows defining much more text properties.
