Document Rendering Styles

This preference panel controls the options for rendering text in Grail viewers. The controls are:

Font size group
Select the general text size, from "tiny" to "huge".
Font family
Select the font family to be used for all but fixed-width ("typewriter") fonts.
Anchors: underline & colors
Select whether anchors should or shouldn't be underlined. The default anchor colors can also be specified for unvisited anchors, visited anchors, and anchors which you're clicking on.
Hovering: underline & color
Hovering can be enabled or disabled, and the underlining and color settings can also be controlled.

Commitment ("OK" or "Apply" buttons) of setting changes immediately affects active browsers in the Grail session.
