selFontSize
Type: Real
Availability: Not available at design time, read or write at run time
The selFontSize property of the JadeRichText class contains the size of the font used for the selected text. The default value is determined by the system. Fonts that are available with JADE vary, according to your system configuration, display devices, and printing devices.
Although you cannot set this property to CharacterFormat_Undefined (#80000000), this value indicates that the selected text contains multiple characters with different font sizes.
