Syntax: !helpfont fontfamily-sizeThis specifies the default proportional font family used in HTML viewer (help) windows, and applies to Linux/OS X releases only. Under Microsoft Windows, this command does nothing. This is the font used to render most text in the help windows.
If no argument is given, the font reverts to the internal default.
The fontfamily-size is given as a face name, followed by white space, followed by the base pixel size. The internal default is ``Sans 9''.
This command has limited value, as the fonts are most conveniently set with the Font Selection panel available in the Attributes Menu and from the help windows.
