Syntax: !helpfixed fontfamily-sizeThis specifies the default fixed font family used in HTML viewer (help) windows, in Linux/macOS releases only. Under Microsoft Windows, this command does nothing. The fixed font is used to render typewriter and preformatted text.
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 ``Monospace 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.
