Function panels are represented in the Top row by an icon. Also, each individual function group has a switch-icon at the top of its panel with which it can be selected. But where do these icons (as well as their help-texts) come from? They are built into in the CXmy modules, which bring with them suggested samples for both types of icons. If there is a requirement for such an icon (for a new entry in the Top row or the creation of a function group), then a suitable proposal is adopted from the relevant module. The CXmy editor permits subsequent rearrangement of the icons as well as changes to the associated help-texts.
